To realize multiple false targets deception jamming against stepped-frequency ISAR, a method of synthesizing multi-false-targets signal for countering stepped-frequency ISAR is proposed, and the scheme of the image synthesizer to produce multi-false-targets signal against stepped-frequency ISAR is given in this paper. The multi-false-targets signal synthesis theory and system architecture of the image synthesizer is firstly described in detail, furthermore, it is illuminated using the synthesis process of two and three false targets. Then, the simulations to synthesize multiple false targets have been done, and the multiple false targets deception jamming against stepped-frequency is accomplished. The simulation results show that multiple false targets are produced successfully, and this method is effective and feasible.

This paper presents the design of the matching network of a 60-GHz high-gain LNA. Through analyzing commonly used structure, a simplified input matching network was designed and an inter-stage matching network was proposed to improve gain and reduce noise. Simulated in 0.13-μm SiGe BiCMOS technology, the LNA provides a gain of 20 dB with a noise figure of 5 dB while consuming 3 mA from a 2.5-V supply.

A high speed pulse detector at W-band is analyzed and designed based on hybrid integrated technology. The beam lead detector diode HSCH-9161 is adopted. The tested results show that the rising time of the output pulse within 92~98GHz is less than 2~3ns after the modulator and detector when the input modulating pulse signal rise time is 700ps. Due to its fast response speed, this detector can be applied in a variety of W- band pulse detecting systems.

In this paper, an analytical method for calculating the complex propagation constant of substrate integrated waveguide (SIW) is proposed, which is based on the scattering theory of the infinite grating of conducting circular cylinders. Making use of this method, the dominant mode propagation characteristic of SIW is calculated and used for the design of SIW. The calculated results are compared with published results and the agreement verified the accuracy of this method.

We carried out the modeling of silicon CMOS on-chip spiral inductors based on an n-ges4 equivalent circuit. Due to the distributed nature of the inductor, the n- (nges4) structure can be more precisely characterize the inductor behavior as compared to the conventional single-pi or double-pi models with an operating frequency beyond the GHz range. The parameter extraction with a characteristic-function approach for the equivalent circuit is achieved through the transformation of the ABCD-matrix.

We have developed two-elements 0.3K high sensitive bolometer detectors system optimized to Multi- Fourier Transform interferometer (MuFT) to realize the multiplying type bolometric astronomical interferometer in millimeter and submillimeter wave bands. A wiregrid polarizer is set in the detector system. The signal led to the bolometer detectors system is then divided into two parts. One of the two bolometer elements receives the reflected signal while the other receives the transmitted signal. Since phases of mutual coherence functions in two signals are shifted 71 ,the difference of reflected and transmitted signals reproduces full mutual coherence function and can easily remove the baseline fluctuations. This method is for the first time succeeded in moon observation at Nobeyama Radio Observatory, Japan, 2007.

This paper presents the research and development of ultra-wideband (UWB) noncoherent transceivers in UWB consortium of USTC. A single band impulse radio transceiver and a multi-band impulse radio transceiver with discrete devices were implemented. Both of the transceivers use FPGA to perform baseband process. The high rate of 190 Mbps wireless transmission of real-time no compression video and HDTV were also verified by using USB2.0 over UWB.
