Performance analysis of a radar signal processing system with continuous electronic array scanning

The paper presents a detailed analysis of a class of signal processing systems with continuous electronic array scanning in the presence of additive white Gaussian front-end receiver noise. In particular, it presents: 1.(1) a unified treatment of frequency-modulation and time-modulation scanning systems by using a set of orthogonal functions,2.(2) the development of a generalized formula for the beam-sampling signal and its properties, and3.(3) a performance evaluation of the system for estimating the unknown angle of arrival of the received signal. It is shown that for the detection and decision criteria chosen for the analysis, the system exhibits a threshold effect determined by the received signal-to-noise ratio, the number of receiving elements in the array, and the number of pulses integrated at the envelope-detector output.
