Synthetic wideband pulse Doppler radar

The synthetic wideband pulse Doppler (PD) radar can simultaneously achieve high range and velocity 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 complex 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 radar 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 series of experiments.
