Abstract

In Pulsed Doppler radar, when wideband signals are used and the target radial velocity is high, linear range migration occurs and cannot be neglected. The migration misaligns the range profiles within a coherent processing interval and degrades the coherent integration gain eventually. On the other hand, Doppler ambiguity must be resolved when the radar uses low or medium pulse repetition frequency. In the paper, Keystone transform is used for range migration compensation. Also, a parallel searching scheme of Doppler ambiguity resolution is proposed based on Keystone transform. The simulation shows the advantages of the algorithm.
