Abstract

We present the matched illumination waveform design for improved target detection and identity discrimination in through-the-wall radar imaging and sensing applications. We consider a multistatic radar system for detection and identification of stationary targets with known impulse responses behind walls. The stationary and slowly moving nature of typical indoor targets relaxes the orthogonality requirement on the waveforms, thereby allowing sequential transmissions from each transmitter with simultaneous reception at multiple receivers. Numerical electromagnetic modeling is used to provide the impulse responses of a human and a wooden table for different target orientations and at various incident and reflection angles. Simulation results, depicting an improvement in performance of the multistatic radar as compared to monostatic operation, are provided.
