Adaptive waveform design for imaging MIMO radar systems

One limitation of MIMO imaging radar systems is the waveform diversity available for the transmitters. Indeed, different properties for the transmitted signals, such as orthogonality and Doppler tolerance, are required in order to obtain good imaging quality with the radar system. This paper investigates the optimization of coded waveforms such as the OFDM and DFCW waveforms. First we demonstrate that DFCW is suitable to be used for radar imaging application, then an optimization procedure for the coding sequence is proposed for a MIMO imaging radar application.
