Abstract
Provided is a method for solving radar ambiguity and occlusion based on an orthogonal two-phase coded signal. The method includes: generating and optimizing an orthogonal two-phase coded signal set by means of a walsh matrix and a genetic algorithm, and alternatively, obtaining an orthogonal two-phase coded signal set through an exhaustive method, depending on a chip length; determining the radar period and the number m of transmission pulses in a period according to the radar farthest detection range and the pulse repetition interval (PRI), and selecting m signals from the orthogonal two-phase coded signal set, to constitute a group of orthogonal two-phase coded pulse signals; and accumulating echoes of transmitted pulse signals, to generate an echo matrix, performing frequency domain pulse compression, to obtain a processed new matrix, and performing moving target detection on the matrix.
