Design and simulation of the cognitive radar for extended target using MATLAB

The cognitive radar is intelligent radar. In this paper, optimization of received waveform for the cognitive radar to estimate the extended targets in the presence of the clutter is discussed. The echo signal back to the radar is convolution between transmitted waveform and each extended Target Impulse Response (TIR) and convolution between transmitted waveform and clutter in the environment. A two step method is used to minimize the echo signal. The first step includes minimization of mutual Coherence individually for every extended target. The second step includes weight vector optimization by maximum iteration method. Finally optimized transmitted Waveform generated gives an accurate results and with better detection.
