提出了一种估计随机步进频率脉冲序列雷达中多个运动目标距离和速度的新算法。该算法采用迭代交替投影技术，具有较高的距离-速度分辨率和接近Cramer-Rao界的估计精度。还可以减轻随机化的步进频率波形的旁瓣基座问题。仿真结果表明了该算法的有效性。
A novel algorithm for estimating the ranges and velocities of multiple moving targets in randomised stepped-frequency pulse-train radar is presented. By using the iterative alternating projection technique, this algorithm can achieve high range-velocity resolution and estimation accuracy close to the Cramer-Rao bounds. The sidelobe pedestal problem of randomised stepped-frequency waveforms can also be mitigated. The effectiveness of the algorithm is illustrated with simulation results.
