Effect of high velocity target on range profile and correction method

To investigate the problem of serious influence of compressed echo pulse widening caused by target's high velocity on the range profile quality, a correction method based on a fast estimation of multi-component LFM parameters is proposed. Firstly, a multi-scatter echo model of the high resolution radar is built. The quantitative analysis of effect of the target's high velocity on the echo is given based on the model. Then the fast estimation method of multi-component LFM parameters is proposed to estimate the change of echo caused by the high velocity and correct the change. Simulation results show that the method can reduce the influence of high velocity on the range profile efficiently and has good robust property.
