Digital Pulse Compression (DPC) is one of the key steps in the signal processing of a radar system. It provides range resolution of the radar system as well as Signal to Noise Ratio (SNR) improvement of the received signal. To get higher SNR improvement by DPC, higher number of phase coded samples in the transmit pulse are required. Traditionally, it is implemented by Finite Impulse Response (FIR) filtering method. This leads to large number of taps (multipliers) of FIR filter, thus limiting the number of samples in the transmit pulse. With the advancement of technology, hardware implementation of higher number of FFT point operation is possible and hence fast convolution is preferred solution for DPC implementation. But, for high unambiguous range radars, large number of samples in the receive window leads to larger numbers of Fast Fourier Transform (FFT) points, thus, consumeing a huge portion of FPGA resources. This paper presents the approach of implementing Digital Pulse Compression via Fast Convolution using FFT - Overlap Save method (FFT-OS). This method will allow us to increase the number of samples in the receive window as well as reduce the length of FFT points to perform fast convolution.

Harmony in variety i.e. unity without similarity is a concept inspired from ancient times. Thinkers propose a team approach based on the same concept for problem solving i.e. using a combined group of solvers to resolve a difficult problem. Neural network ensemble (NNE) is a concept based on the same approach. Multiple artificial neural networks (ANNs) are trained for the same dataset to give the appropriate measured resonant frequency from the relative parameters of rectangular microstrip antenna (MSA). The previous experimental works' MSA datasets have been used for training of ANNs. Genetic Algorithm (GA) is employed to compute the optimum subset of ANNs which perform better than rest available to constitute an ensemble. A model of resonant frequency of MSA is established by using this NNE approach and the results have been compared with some previous works.

Natural vegetation cover and crop yield vary spatially and temporally in a diverse manner. Understanding this variation requires a robust analysis of important climatic factors such as rainfall, temperature, sunshine hours etc., along with LULC dynamics. In this study, NDVI has been used as an indicator of vegetative greenness and productivity. Based on 0.5°×0.5° spatial resolution data of NDVI obtained from MISR, correlation between NDVI and average seasonal precipitation has been analyzed. The precipitation data used is obtained from two sources, TRMM 3B42-V7 and IMD gridded data, both at spatial resolution of 0.25°×0.25°. The TRMM and IMD data have also been mutually correlated. Data was acquired for the months of June, July, August and September (JJAS) i.e. monsoon season for 14 years, 2000 to 2013. The correlation coefficients thus obtained are reported significant at a confidence level of 99% (p<;0.001).

Efficient compression and transmission of electrocardiogram (ECG) data is a prime concern to monitor a heart patient's health from rural areas. Research has been carried out for this from last several decades to present. There are many algorithms which have been developed for this and it plays a vital role for telemedicine applications. This paper presents a compression performance analysis based on hybrid transform methods which provide higher compression ratio than single stage transform method. To implement hybrid transform method, combinations of two transforms have been used. Fast Fourier transform, discrete sine transform and discrete cosine transform have been used at transform 1 stage whereas discrete wavelet transform has been used at transform2 stage.

This paper proposes a microstrip wideband bandpass filter using `U' shaped defected ground structure (DGS). It consists of four coupled U shaped slots etched on the ground plane and is fed by parallel coupled `T' shaped microstrip feed lines on the top. The gap between T shaped feed lines act as an inverter which will convert bandstop response to bandpass response. Due to the arrangement of etched slots and due to cross coupling between these slots, the Alter exhibits two transmission zeros on either side of the passband, thereby improving selectivity of the filter on both sides of the passband. Prototype filter simulated shows an insertion loss of 1.15 dB with fractional bandwidth (FBW) of 29.73% centered at 5.75 GHz. The designed filter has the benefits of low insertion loss, high selectivity, low cost and is easy to fabricate, which can be used for modern wireless communication systems.

This paper presents an Ultra-Wideband (UWB) fractal antenna and a dual-band antenna integrated on a single substrate for cognitive radio applications. The UWB fractal antenna has an impedance bandwidth of 112.05%. The dual-band antenna has a bandwidth of 2.17% (3.503 GHz-3.58 GHz), suitable for WiMAX applications, and 2.32% (5.96 GHz-6.1 GHz) with resonant frequencies at 3.525 GHz and 6.02 GHz respectively. The dual-band antenna has a gain of 0.86dB and 2.27dB at frequencies of 3.525 GHz and 6.02 GHz respectively. Shorting pins are used in the antenna to reduce surface wave and to increase isolation between the two antennas. The isolation between the two antennas is found to be below -25 dB at 3.525 GHz and 6.02 GHz. The antenna has a compact dimension of 70mm × 50mm (1.16λ × 0.83λ). The observed VSWR value of the UWB antenna and the dual-band antenna is less than 2 for the required frequency range.

A design of 2×2 broadband circularly polarized (CP) antenna array is proposed to resonate within S-band at 2.4 GHz for wireless applications. To realize broadband operation, multiple slots of variable length are embedded in antenna array patch geometry. The individual array patch is excited by microstrip feed lines, which are derived from power divider circuits. The whole feeding structure is designed with sequential phase (SP) of 00, 90, 180 and 2700. The proposed multi-slot array structure gives the advantage of being wide impedance and axial ratio bandwidth with high gain. The -10 dB reflection coefficient bandwidth and 3 dB axial ratio (AR) bandwidth are 86% (1.68 GHz-4.22 GHz) and 29% (2.99 GHz-4.02GHz), respectively. Good radiation characteristics with gain more than 10 dBi in the operating region are obtained.

In-flight sensor Modulation Transfer Function (MTF) can be measured using ground based targets (natural/artificial) which satisfy the basic criteria. Meeting the specific conditions all the time is practically difficult. In this paper, we have explored Bi-resolution method to measure ResourceSat (RS)-2 Linear Imaging Self Scanner (LISS)-III sensor MTF. LISS-III sensor MTF was measured for three spectral bands (B2, B3 & B4) with corresponding LISS-IV bands as reference. MTF values determined for all three data sets found to meet the specifications and their variation were within 6.1% over the mean.

A miniaturized microstrip lowpass filter design using elliptic function is presented in this paper. The proposed filter has a cut-off frequency of 2.5 GHz with passband ripple 0.1dB and stopband insertion loss greater than 20dB at 2.85 GHz. It provides two finite attenuation poles at 2.945 GHz and 4.015 GHz in the stopband having attenuation of the order of 35dB and 50dB respectively. Different types of design characterization have been investigated of the proposed filter and a comparative study based on design parameters and dimensions has been provided.

The paper presents analysis of Kerr nonlinear impairments present in long haul Wavelength Division Multiplexing (WDM) links and their compensation. A framework is proposed for transmission impairments compensation in optical domain by Optical Back Propagation (OBP) technique. In this technique, effective negative Kerr nonlinear coefficient is achieved using highly nonlinear fibers (HNLFs) and results depict that in nonlinear transmission regime, computational complexity is reduced by implementing OBP compared to digital back propagation (DBP).
