Adaptive waveform and sampling interval tracking based on estimation accuracy for Doppler radar

An adaptive maneuvering target tracking algorithm for Doppler radar is proposed, where both the sampling interval and transmitting waveform can be adjusted according to the predicted error covariance output from IMM filter adaptively. Compared with tracking algorithm of fixed sampling interval or transmitting waveform, the adaptive tracking algorithm can save the consumed system resource effectively on the guarantee of tracking performance.
