Abstract

The invention discloses a multidirectional matching signal generation method based on spectrum synthesis. The method comprises the steps that spectrum component synthesis on signals of a target in multiple matched detection orientations is carried out; a transmitting waveform with good detection performance for multiple azimuth detection angles is designed for radar detection, the radar early warning detection capability is greatly improved, the adaptability is high, the viewpoint is novel, the detection early warning capability of a radar system is greatly improved, and an effective technicalmeans is provided for target detection and anti-stealth design.

Description

technical field [0001] The invention relates to the technical field of radar detection signal matching generation, in particular to a multi-directional matching signal generation method based on frequency spectrum synthesis. Background technique [0002] Low-observable targets have weak backscatter echo (RCS) in the high-frequency region, which greatly reduces the amplitude of target scattering echo, and conventional detection methods cannot effectively detect and identify low-observable targets; that is, with the detection Sensitivity and identification accuracy are high requirements, and conventional radar high-frequency detection signals cannot meet the early warning and identification requirements of low-observable targets. Moreover, the radar scattering echoes of low-observable targets are quite different at different azimuth angles, the matching detection waveform (matching detection signal) cannot cover multiple azimuth detection angles, and the early warning and dete...
