The main practical performance of sparse-array synthetic impulse and aperture radar

Sparse-array synthetic impulse and aperture radar(SIAR) has large sparse arrays and uses the technology of digital synthetic impulse and aperture of array. It can keep the advantage of traditional meter-wave radar and overcome most of its disadvantage.lt is a new kind of advanced digital array radar with synchronously multifunction, low probability of interception,capacity of long-time coherent integration of targets and fine doppler resolution , high feasibility of system processing.etc. Here ,the SIAR´s ability of low-altitude target detection, low probabilities of interception and anti-jamming is researched for sufficiently understanding its main practical performance.
