Abstract

Our scope in this paper is to analyze the performance of a radar signal processor that consists of a nonrecursive MTI followed by a square-law integrator and a CFAR circuit detection, the operation of which is based on the double-threshold procedure. The processor performance is evaluated for the case where the background environment is assumed to be ideal (homogeneous) as well as in situation where it contains a number of interferers along with the target under test (multitarget environment). For some specified values for the first threshold, it is shown that the processor detectability loss is very low, and the performance degradation, caused by spurious targets is quite small even if their number is large. Additionally, the processor performance improves as either the number of incoherently integrated pulses increases or the correlation between consecutive sweeps decreases, as we predict.
