Dual-channel pulse compression processing is a common processing process for radars to achieve synchronous measurement of target distance and angle, and the pulse compression ratio is an important indicator to measure the effect of pulse compression. For the test of pulse compression ratio, the existing technology usually uses manual setting of the pulse width, pulse repetition period, carrier frequency, modulation bandwidth and other parameters of the arbitrary signal generator to generate an input signal that matches the pulse compression processing characteristics of the radar under test, and obtains the output signal envelope after pulse compression through the radar signal processing system analog / digital sampling, compression, detection processing and other processes, and manually tests the output signal pulse width through an oscilloscope. Calculate the ratio of the output pulse width parameter of the arbitrary signal generator and the output signal pulse width manually tested by the oscilloscope to obtain the pulse compression ratio value.
