Abstract

The invention discloses an ultra-wideband radar target detection method, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target time domain echo signal; extracting pole information of the target time domain echo signal by adopting an ultra-wideband advanced time frequency analysis method; according to the pole information, acquiring echo signals atdifferent azimuth angles by adopting a multi-azimuth matching synthesis method; performing time inversion on the echo signals at different azimuth angles to obtain inversion echo signals, and transmitting the inversion echo signals as transmitting signals to obtain matched echo signals; and performing matching result evaluation on the matching echo signal to obtain an identification result. According to the invention, the signal-to-noise ratio of the target echo can be improved, so that the purpose of identifying or detecting a weak and small target in the presence of noise and interference isachieved.

Description

technical field [0001] The invention relates to the technical field of ultra-wideband radar target recognition, in particular to an ultra-wideband radar target detection method based on multi-directional matching and synthesis based on time-frequency analysis, electronic equipment and a storage medium. Background technique [0002] Ultra-wideband radar target recognition technology has developed into an important branch of the radar field, and target recognition is one of the ultimate goals of studying radar target characteristic signals. In many military fields that design national security, such as precision guidance, battlefield surveillance, and anti-missile and anti-defense, radar target recognition is one of the core technologies that determine the intelligence of weapon systems, and it is also a bottleneck that restricts the development of intelligent weapons systems. [0003] In the optical area, the complex target can be regarded as an extended target composed of ma...
