摘　　要：欺骗干扰作为一种典型的有源干扰,在距离维或多普勒维上产生虚假目标,使雷达发生虚警,严重影响雷达正常工作。针对速度欺骗干扰,该文提出了一种基于脉间波形幅相联合设计的抗速度欺骗干扰方法。首先,根据速度欺骗干扰下的雷达回波模型,建立最小化阻带内干扰能量与目标旁瓣能量的加权和的优化准则,同时考虑离散量化相位和峰均功率比(PAR)约束,形成脉间幅相联合设计抗速度欺骗干扰的优化问题;然后,提出非精确交替方向惩罚法(IADPM)算法求解该优化问题,并分析算法的计算复杂度;最后,仿真实验分析验证了该算法的有效性。Deceptive jamming as a typical active jamming,produces false target on the range dimension or Doppler dimension,which increases probability of false alarm and significantly degrade the performance of radar.This paper is focused on the joint design of pulse amplitude and phase against velocity deceptive jamming.In particular,a design criterion incorporating a weighted sum of jamming energy and target sidelobe energy in the stopband is developed to minimize under phase quantized and peak-to-average power ratio(PAR)restriction.To tackle the resulting non-convex optimization problem,a new inexact alternating direction penalty method(IADPM)is proposed based on the ADPM framework and the computational complexity is analyzed.Finally,numerical results are provided to demonstrate the effectiveness of the proposed methodology.
