one of the problems in detecting radar targets is the variation of target cross section due to aspect angle; which is named as target fluctuation. this perfectly depends on target geometry and transmitted wavelength and can cause significant loss of detection. one of the solutions to this is improving the radar range resolution. stepped frequency is one of the signals that can improve the range...

because of having good performance in cancelling the clutter echoes, pulsed-doppler radar is the best solution in some applications. in this paper a new algorithm for signal design and signal processing in high prf radar is developed. the robust chinese remainder theorem is the basis for estimating the unambiguous ranges in the proposed algorithm. two high prf pulsed-doppler radars are designed...

Software infrastructure is a growing part of modern radio science systems. As part of developing a generic infrastructure for implementing Software Radar systems, we have developed a set of reusable signal processing components. These components are generic software based implementations for use on general purpose computing systems. The components allow for the implementation of signal processi...

Cognitive radar is a new paradigm to conceive the next radar generation characterized by unique and amazing features inspired to mental abilities and processes related to knowledge. Introduced by Haykin [1] and Guerci [2], it is attracting huge attention within the radar community during the last few years. The key concept is that radar system performance can be enhanced through a continuous an...

based on the compressed sensing theory, if a signal is sparse in a suitable space, by using the optimization methods, signal could be accurately reconstructed from measurements that are significantly less than the theoretical shannon requirements. the sparse representation may exist for the signal and it is not available for the noise; this could be used to distinguish these two. on the other h...

In this paper , the use of adaptive weights over the radar measurement dimensions of pulse time, antenna receive element, and wideband frequency is extended to cover a much broader range of radar detection problems than was supposed in the original formulation of spacetime adaptive signal processing (STAP). These problems include, among others (1) Adaptive beamforming in three dimensions; (2) D...
