There are a number of potential applications for low cost short range phased array radar sensors: ship bumpers, large vehicle sensors and level crossing obstacle detection for example. Phased arrays have the benefit of reduced size and the elimination of moving parts compared with more traditional rotating antenna systems. Another potential benefit is that the image update rate can be orders of...

The index modulation based on multiple-antenna architecture is a prospective information embedding approach for the joint radar-communication system (JRCS). Current investigations mainly focus applying spatial and frequency in phased array (PA) radar multiple-input multiple-output (MIMO) radar. In this article, we devise an strategy by combining phase random diverse (RFDA) MIMO radar, which can...

Multiple-input Multiple-output (MIMO) radars benefit from spatial and waveform diversities to improve the performance potential. Phased array radars transmit scaled versions of a single waveform thereby limiting the transmit degrees of freedom to one. However MIMO radars transmit diverse waveforms from different transmit array elements thereby increasing the degrees of freedom to form flexible ...

Short-range ambiguous clutter can seriously affect the performance of airborne radar target detection when detecting long-range targets. In this letter, a multiple-input-multiple-output (MIMO) array structure elevation filter (EF) is designed to suppress short-range (SRC). The sidelobe level value in region taken as objective function construct optimization problem and optimal EF weight vector ...
