This paper describes a monolithic integrated single-chip transceiver intended for impulse radio (IR) - Ultra-wide Band (UWB) applications compliant to the IEEE 802.15.4a standard. The transceiver operates in the higher UWB band on the mandatory channel #9 (7.9872 GHz). The implemented nominal data rate is 850 kb/sec. The presented chip consists of the entire RF-front-end, 6-bit-resolution successive approximation register (SAR) analogue-to-digital converter (ADC), and the baseband processor running with a clock of 31.2 MHz. The analogue frontend can be further segmented into a pulse generation and transmit part and a quadrature direct down conversion receiver part, whereas both parts share a frequency synthesizer based on an integer-N phase-locked loop (PLL). The impulse generation is based on the gated oscillator principle allowing required on-off keying (OOK) as well as binary phase shift keying (BPSK). While the receiver supports both, coherent and non-coherent impulse detection, here only non-coherent operation will be presented. The baseband processor part contains a separated 499.2 MHz clocked block for transmitter control and provides a serial peripheral interface (SPI) for data exchange with an external micro controller. The presented chip was fabricated in a 0.25 μm SiGe:C BiCMOS technology occupying a Si area of 3.25 - 3.25 mm2.

This paper presents an analysis of the power consumption of the UWB PHY layer of the IEEE 802.15.4a standard. This work focuses on the transmitter PHY layer implementation. The influence of the different modes settings on the power consumption is investigated. The considered implementations use an FPGA coupled with an UWB pulse generator implemented in an ASIC. The first PHY layer implementation is fully integrated in the FPGA. The consumption study reveals that the system consumption is reduced with the Mean PRF of 3.9 MHz due to the lower number of emitted pulses. The study also shows that the highest power consumption is due to the 499.2 MHz clock. The second implementation proposes to move the 499.2 MHz clock into the ASIC to reduce its consumption. For the mandatory data rate and the 3.9 MHz Mean PRF, this technique reduces the energy by emitted bit from 2574 pJ to 727 pJ.

This paper presents the design of a 2-16 GHz ultra wideband low noise amplifier (UWB LNA). The proposed UWB LNA employs a symmetric 3D RF integrated inductor. The UWB LNA has a gain of 11 ± 1.0 dB with NF less than 3.25 dB. Good input and output impedance matching and good isolation are achieved over the operating frequency band. The proposed UWB LNA is driven from a 1.8V supply. This UWB LNA is designed and simulated in the standard 0.18 μm CMOS technology.

Ultra-wideband signals are used to examine multiple-constituent fluid mixtures in a semi-open system. A feedforward neural network operates on an array of easily computed signal properties, plus the weight and temperature of the fluid samples, to provide an estimate of the constituent proportions. The average performance of the neural network is tested by artificially increasing the test data sample size and repeatedly training neural networks of the same topology. Networks of differing topologies are compared. Statistical analysis is performed on these results and the 95% confidence interval of the data prediction is shown. The 95% accuracy averages around ± 6.9 percentage points for both oil and water.

Constant false alarm rate (CFAR) methods are generally applied for the target detection after clutter mitigation in the through-wall sensing applications using ultra-wide band through-wall radar. Current studies of CFAR only focus on detection of moving human targets without considering the effect of residual clutters. However, in the cases with the presence of strong stationary clutters, little residual clutters after clutter mitigation are strong enough to cause false alarms in the following target detection, compared with the weak human target echoes. Unfortunately, conventional CFAR methods fail to remove the effect of residual clutters and suffer from false alarms. To combat this problem and obtain a reliable detection performance, a moving target CFAR detection method along slow-time profile is proposed in this paper. Experiments with an impulse through wall radar show that the proposed method not only has good detection performance for moving human targets, but also successfully gets rid of the problems brought by the strong residual stationary clutters.

An all-electrical, low-cost, wideband chip-to-chip link on a multi-mode dielectric waveguide is proposed. The signal is coupled from the silicon chip to the fundamental and polarization-orthogonal degenerate Ex11 and Ey11 waveguide modes using planar electric and slot dipole antennas, respectively. This approach doubles the capacity of a single line without sacrificing robustness or adding implementation cost and complexity. Two independent ultra-wideband 30GHz channels, each from 90 GHz to 120 GHz, are demonstrated. The large available bandwidth will be channelized in frequency for optimal overall efficiency with a CMOS transceiver. Various design aspects of the structure are examined and discussed. The proposed waveguide offers a solution for Terabit-per-second (Tbps) electrical wireline links.

A novel fast time-domain approach called bistatic fast factorized backprojection algorithm (FFBPA) for general bistatic low frequency ultra wide band (UWB) synthetic aperture radar (SAR) imaging is proposed. This method is able to accurately dispose the azimuth-variance of range cell migrations and motion errors in general bistatic SAR imaging and achieve the imaging efficiency in parity with frequency-domain methods. It represents subimages in elliptical polar coordinates to reduce the number of operations. Taking into account motion errors, the sampling requirements of the elliptical subimages is deduced by analyzing the bistatic range error. The implementation and computational load of the bistatic FFBPA (BFFBPA) are discussed. Simulation results are shown to demonstrate the correctness of the theory analysis and the validity of the proposed method.

Compressed sensing (CS) is an emerging technique which enables sub-Nyquist sampling of sparse or compressible signals. The application of CS theory in the impulse radio ultrawideband (IR-UWB) receiver design has recently attracted much attention. This paper provides an exploration of the CS-based IR-UWB receiver from different aspects: front-end hardware architectures, back-end signal processing algorithms as well as application scenarios. And the performance of the CS receiver regarding the number of CS measurement and different CS recovery algorithms is evaluated and compared against the conventional sub-Nyquist sampling receiver based on energy detection (ED) scheme. Moreover, a strategy to improve the CS receiver performance in handling UWB signals with heavy noise and multipath propagation is proposed.

To estimate the time of arrival (TOA) of the first path (FP) in ultra wideband (UWB) ranging, we propose an entropy based method. In the energy detection (ED) receiver, thresholding crossing (TC) is used a lot to detect the FP. The threshold should be carefully chosen, or else the false alarm rate will be high. Our method detects the FP from a different angle based on the arrival characteristics of the dense multipath, which is that the FP is always followed by many other strong paths. During a short interval, the TOAs of these paths are definite and the samples which contain these multipath signals can exceed the suboptimal threshold in most cases, while the TOAs of the few TC noise samples before the FP are random. We use the entropy to measure the randomness of the distribution of the last TC sample before the current one. Then the FP is determined by choosing the sample which has very large entropy and is followed by a sample with very low entropy. Simulation results verify its effectiveness with IEEE 802.15.4a Standard.

Ultra-wideband Synthetic Aperture Radar (UWB SAR) has the characteristics of wide aspect angle and wide frequency band. UWB SAR data contains rich information about targets. However, the prior information of landmine is used until the discrimination in the conventional landmine detection procedure. Therefore, in order to ensure the probability of detection, there exist many false alarms in the prescreening results. That will increase the burden of the subsequent processing steps. By applying the prior knowledge of landmine to imaging, landmine-enhanced imaging can be realized and beneficial improvements in image quality and detection performance can be expected. In this paper, the unique feature of aspect invariance is used in landmine-enhanced imaging. Further, we apply the landmine-enhanced imaging to landmine detection. Thus, the detection probability of landmine increases under the same false alarms rate as the traditional landmine detection method. The experimental results demonstrate the effectiveness and practicability of the proposed algorithm.
