Abstract

The principle of forming digital multiple receiving beams in phased array radars is discussed

using the theory of digital signal processing. The digital phase distribution network method and FFT beam forming network method are suggested. A simulating test with the DJS-130 computer is made to verify the correctness of these methods. As an example

the antenna patterns of four adjacent beams without or with receiver noise have been calculated and shown in graphs. The possible applications of these methods in phased array radar systems are also mentioned in this paper.
