The conventional phased array cannot effectively suppress the interferences that have the same direction angle but different ranges of the targets. To overcome this disadvantage, frequency diverse array (FDA) is proposed in recent years. However, FDA beampattern is time-variant, which makes targets illuminated only in a very short duration and causes poor detectability of targets. This letter presents...
Detection of blind spot area of an intelligent mobile vehicle is presented in this paper. In order to scan the concerning area, a phased array radar is designed. The approach is of two fold. Firstly, microstrip phased array antenna with progressive phased shifter is designed and subsequently, it is optimised for improvement of performance through parametric studies and array distribution using Tchebyscheff...
For bistatic synthetic aperture radar (Bi-SAR) with phased array antenna and arbitrary bi-static geometry configuration, this paper proposes a clutter modeling method for clutter suppressing and ground moving target detection. Furthermore, based on the simulated space-time clutter spectrum of four typical specific geometry configurations, the detailed analysis is also given for the clutter suppressing...
To investigate the problem of complexity and diversity of the radio frequency signal caused by phased array radar, the analytical method analyzing the reconnoitered data of the radar radio frequency signal on real-time signal simulation is present in this paper. The phased array technique used in typical phased array systems is analyzed. The radar radio frequency signal is simulated by Matlab7.0 on...
Large ultralow sidelobe airborne array antennas are required for detection of low radar cross section targets against a background of complex clutter and jammer interference. One of the critical factors which limits the clutter and jammer suppression performance of adaptive phased-array radars is the impact of the aircraft in the near-field of an ultralow sidelobe antenna. A simulation featuring a...
