An Adaptive Noncoherent Processor for Multi-Channel Radars,

Abstract

An adaptive noncoherent processor (ANCP) system, intended as an ECCM for multi-channel (e.g., frequency agile) radars operating in a jamming environment, is described. The ANCP system operates by estimating the noise power in each active channel of the radar, adaptively adjusting the channel gain, and then noncoherently combining the outputs of the channels before executing a single target present/notpresent threshold detection. An example of the theoretical performance of an ANCP system in the presence of white-noise jamming with Gaussian statistics is presented. It is shown that a practical system performs within 3 dB or better of an ideal optimum system using prior knowledge of the jamming and target powers. The report concludes with appendices outlining the mathematical techniques for computing these results.
