Abstract :
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 target´s 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 calculation 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 simulation results verify its effectiveness.
