A robust adaptive detection scheme for radar Doppler processing

Adaptive detection procedures offer significant advantages with respect to conventional (data-independent) processing, particularly in structured interference environments that are commonly encountered in practical radar applications. This paper illustrates the use of adaptive Doppler processing for main beam interference cancellation, where it is the temporal (pulse-to-pulse) structure rather than the spatial structure of the interference that is exploited to achieve performance gains relative to conventional Fast Fourier Transform (FFT) based approaches. The experimental performance of a generalized adaptive detector, that exhibits robustness against mismatched targets as well as unwanted signals in structured interference environments, is compared against conventional FFT-based Doppler processing and modern adaptive detection schemes that have also been derived using the generalized likelihood ratio test (GLRT) methodology [1].
