摘　　要：将雷达的频率捷变技术与相参技术相结合,分析了在频率捷变条件下,运动目标回波相位的变化规律。影响相参积累的因素包括因频率捷变带来的回波中载频与距离及速度的两个耦合项。并在此基础上提出了利用相位补偿原理来进行有效相参积累的方法,主要包括参差脉冲重复间隔法及基于代价函数的补偿法。算例表明了方法的可行性、通用性,具有一定的理论和实践指导意义。Frequency agility and coherent process technique used in radar are combined.In this context,the phase changes of the moving target echo are analyzed.Factors affecting the coherent include two coupling terms,carrier frequency versus range and carrier frequency versus velocity.Effective coherent methods on phase compensation are proposed,which include the irregular pulse repetition interval method and the cost-function based compensation method.The feasibility and versatility of this method are verified.
