During the last decade, considerable progress has been made in radar signal processing, and this report states its present status. The three broad areas of coherent processing, noncoherent detection, and track-while-scan systems are discussed. Specifically, in the area of coherent processing the subjects of sidelobe cancelers, adaptive radars, MTIs, and doppler processing are discussed. In the adaptive processing area, both the maximum signal-to-noise and least mean-square methods are described, and special emphasis is given to the problem of convergent rate. The moving-target detector MTD is used as an example of doppler processing. In the area of noncoherent detection, various integrations are discussed. Among these are the moving window, feedback integrator, two-pole filter, binary integrator, and batch processor. Methods of obtaining a constant false-alarm rate using either adaptive thresholding or nonparametric detectors are also considered.
