Motion compensation method for high speed target based on space-time-frequency joint processing

According to the problem of motion compensation in long time integration, the echo model of high speed target in phased array radar is derived, and the equation is simplified while the target distance and angle are time varying. On this basis, an signal processing algorithm based on space-time-frequency joint matched filter is proposed, and the influence of beam-forming methods on Doppler matching is analyzed. The validation of theory is verified by simulation results.
