摘　　要：针对脉冲多普勒体制的相控阵雷达,利用交互多模型方法,分析了径向速度对相控阵雷达跟踪性能及雷达资源管理的影响。结果表明,在相同条件下,引入径向速度量测不仅可以减少跟踪机动目标时所使用的雷达资源,而且可以显著改善目标的跟踪精度,机动越大,性能改善越多。在工程实现上,应采用引入径向速度的变采样间隔跟踪滤波器。Analysis of tracking performance and resource management for pulse doppler phased array radar is done by simulation with incorporating radial velocity into the IMM filtering. Simulation results show that the radar resource utilized in tracking maneuvering target will be saved and the tracking accuracy will be greatly improved via incorporating the radial velocity measurements under the same condition. The more maneuvering the target is ,the more accurate the tracking performance will be. The tracking filter incorporating the radial velocity and varying sampling interval concept should have a practical application in engineering.
