摘　　要：合成宽带脉冲多普勒(pulse Doppler,PD)雷达可以同时实现距离和速度二维高分辨;具备良好的相参特性,利用相推原理能实现极高的测距和测速精度,可用于复杂目标多部件微动测量;具有较强的抗杂波和抗干扰性能。阐述了合成宽带PD雷达体制及其主要信号形式,介绍了合成宽带PD雷达的距离速度二维高分辨实现原理,总结了合成宽带PD雷达的主要特性,最后通过一系列实验验证了合成宽带PD雷达的微动测量能力、高精度测距测速能力和相参ISAR成像能力。The synthetic wideband pulse Doppler （PD） radar can simultaneously achieve high range and ve- locity resolution. And it has good performance of coherence, so high range and velocity measurement precision can be achieved by using the phase derived principle and it can be applied to micro-motion measurement of com- plex targets with multi-components. Besides, it has good performance of anti-clutter and anti-jamming. In this paper a synthetic wideband PD radar system and its main signal forms are presented~ the principle of achieving high range and velocity resolution is introduced~ moreover, the main properties of the synthetic wideband PD ra- dar are summarized~ finally, the abilities of the synthetic wideband PD radar, including the abilities of micro- motion measurement, precise range and velocity measurement and coherent iSAR imaging, are verified by a se- ries of experiments.
