TL;DR: In this article, the authors proposed a radar signal real-time detection method, which is characterized by comparing an average amplitude of N sampling points before a certain moment with the amplitude of the sampling point at the moment.
Abstract: The invention relates to a radar signal real-time detection method. The method is characterized by comparing an average amplitude of N sampling points before a certain moment with the amplitude of thesampling point at the moment, and if the amplitudes of the plurality of sampling points after starting of the certain moment are continuously a certain value higher than the average amplitude in a previous certain period of time, considering that a signal rising edge exists at the moment; otherwise, if the amplitudes of the plurality of continuous sampling points after a certain moment is startedare a certain value lower than the previous average amplitude, considering that a falling edge exists at the moment; and when both the falling edge and the rising edge exist, intercepting a signal part existing in data immediately. Whether a signal exists is detected in a mode of judging the rising edge and the falling edge in a time domain, and an effect of detecting the signal in real time under a passive condition can be achieved by setting reasonable parameters and thresholds.
