A Fast Range Migration Compensation Method

摘要：

Coherent integration is usually used in matched filter radar signal processing to improve target signal to noise ratio (SNR), but the accumulation time is restrained by targets motion according to the conventional radar design principle. Keystone transform can correct range migration without the exact value of target velocity and as a result, the SNR is improved through coherently accumulating all pulses. But the usually used interpolation method has very huge cakulation burden. In this paper, a fast range migration compensation method without interpolation based on keystone transform is proposed, which greatly reduce the computational cost, and is more suitable for real-time processing. The sim ulation results verify its effectiveness.
