A fast algorithm for designing the transmitted waveform and receive filter of MIMO radar

The authors study the problem of the transmitted waveform and the receiving filter design for multiple-input multiple-output (MIMO) radar in signal-dependent interference environment. The mean-square error of point target scattering coefficient estimate is considered to represent the measurement of the system. A fast computational approach is proposed to obtain optimal pairs for the transmitted waveform and receive filter. The proposed algorithm basing on fractional programming and power method-like iterations is efficient. Furthermore, this algorithm can address constant modulus constraint and peak-to-average-power ratio (PAR) constraint on the transmitted waveform. The effectiveness of this approach is demonstrated by numerical simulations.
