Monopulse radar velocity measurement function optimization method based on error energy discrimination

Abstract： In this paper, the principle of monopulse radar velocimeter system is described, and the criterion of energy discrimination based on frequency discriminator output signal is put forward because of the phase jump of echo signal, which leads to the broadening of spectrum, the occurrence of error line and the error of velocity measurement. By discriminating the output signal of the frequency discriminator, when the phase of the echo signal continues to jump, the output of the discriminator oscillates, the output of the integrator will exceed the threshold, and the speed measuring system will eliminate blurring again. When the phase of the echo signal is stable, the speed-measuring result can be returned to the correct result, so that the speed-measuring error caused by the jump line can be corrected.
