AI Technical Summary
In existing radar signal processing systems, interference suppression detection is independently distributed across various signal processing stages, resulting in poor detection accuracy and real-time performance, making it difficult to meet the rapid response requirements for variable interference signals in special scenarios.
A signal processing method for multi-dimensional suppression of interference and rapid listening response is designed. This method involves multi-dimensional listening at different stages of the radar signal processing system, including echo, digital down-conversion, pulse compression, moving target indication, moving target detection, CFAR detection, and SAR imaging. By combining energy, frequency, signal characteristics, and statistical detection, the method comprehensively analyzes the existence of interference and performs anti-interference response in real time.
It achieves rapid and accurate suppression of interference identification and response, improves detection accuracy and anti-interference timeliness, and can be seamlessly embedded in conventional radar signal processing systems, thereby enhancing the system's anti-interference capability.
