Waveform design for cognitive radar based on information theory

Optimal waveform design is an important component of cognitive radar, it can transmit the designed waveform to adapt environment. Many researchers focused on the next transmitted optimal waveform design according to the last target impulse response estimation. In this paper, we take advantage of the target impulse response prediction to design the next transmitted waveform for wide sense stationary-uncorrelated scattering target impulse response model based on the mutual information. The target impulse response prediction is derived by the Kalman filter for next transmitted waveform. The simulation results demonstrate the proposed method valid.
