Description

technical field [0001] The invention relates to the field of radar signal processing, in particular to an intelligent compressible radar signal processing system and verification method. Background technique [0002] With the development of radar technology, the sampling rate of radar signal processors continues to increase, the amount of data collected by the ADC increases sharply, and the data is finally stored in solid-state memory. Therefore, an intelligently compressible radar signal processing system has become an urgent problem to be solved. [0003] The main problem of the traditional radar signal processing and compression system is that before BAQ compression, only the fixed DC is eliminated. Once the DC in the radar signal processing system changes with the external conditions, there will be a large residual DC component. Compression algorithm performance has a greater impact. In addition, the traditional radar signal processing compression system does not adapt...

Problems solved by technology

[0003] The main problem of the traditional radar signal processing and compression system is that before BAQ compression, only the fixed DC is eliminated. Once the DC in the radar signal processing system changes with the external conditions, there will be a large residual DC component. Compression algorithm performance has a greater impact

In addition, the traditional radar signal processing compression system does not adaptively adjust the input radar echo power according to the actual working conditions of the system. When the input radar echo signal power is too large or too small, after BAQ compression, the radar echo signal The original signal waveform cannot be restored normally
