The theme of this paper is the cancellation of clutter echoes in modern coherent radar systems. The receiver operating characteristics (ROC) of the following clutter filters are compared: (a) optimum linear filter, (b) the linear filter with Chebyshev tapering, and (c) the non-linear filter which takes the minimum between the outputs of few linear filters which process the same radar signals with...
In this paper, we propose new VLSI architectures for the order statistics (OS) constant false alarm rate (CFAR) detector and the modified OS-CFAR detectors such as the order statistics greatest of (OSGO) and the order statistics smallest of (OSSO) CFAR detectors. By transforming the OS-CFAR detection algorithm to a recursive algorithm, we derive efficient systolic array architectures to achieve good...
