摘要

在匹配滤波雷达信号处理中,通常采用相干积分来提高目标信噪比,但传统雷达设计原则下,累加时间受目标运动的限制。Keystone变换可以在不需要精确目标速度值的情况下对距离偏移进行校正,从而通过对所有脉冲的相干累积提高信噪比。但常用的插值方法计算量非常大。本文提出了一种基于keystone变换的无插值快速距离偏移补偿方法,大大降低了计算成本,更适合实时处理。仿真结果验证了该方法的有效性。

A fast range migration compensation method
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.
