Radar signal micro-feature analysis system based on digital filtering

Abstract

The invention discloses a radar signal micro-feature analysis system based on digital filtering. The system comprises a signal sampling module. The input end of the signal sampling module is electrically connected with a signal reading module. The output end of the signal reading module is electrically connected with a signal processing module, the input end of the signal processing module is electrically connected with a signal analysis module, the input end of the signal analysis module is electrically connected with a processor, and the output end of the processor is electrically connectedwith a signal modulation module, a display module and a digital filtering module. According to the invention, the signal reading module is arranged; unnecessary analysis time can be reduced. By arranging the digital filtering module, sampling signals can be subjected to digital filtering processing, interference signals are effectively restrained, the analysis speed is increased. By arranging thesignal analysis module, parameters of the pulse width, the rising edge and the falling edge can be extracted, pulse compression radar signals with special physique can be analyzed, and the radar signal recognition capacity is improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a radar signal micro-feature analysis system based on digital filtering. Background technique [0002] Radar uses radio methods to detect targets and determine their spatial positions. Therefore, radar is also called "radio positioning". Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate targets and receive their echoes. The distance, distance change rate, azimuth, height and other information from the target to the electromagnetic wave emission point can be obtained from this. The typical frequency band occupied by the radar signal is from 500 MHz to 18 GHz, and the operating frequency of the millimeter wave radar reaches 40 GHz or even higher. [0003] The sorting and identification of complex radar signals has always been a key technology and problem in electronic countermeasures. With the ...
