AbstractA system and method for correcting the quadrature demodulation error of radar are disclosed. The echo signals of MF radar are demodulated by quadrature demodulator. The gain signal and phase signal are output respectively by low-pass filter and sampler, and then processed respectively by autocorrelator and mutual correlator. The resultant signals are output by compensator. Its advantages are high accuracy, and simple method.
