A noncoherent approach to through-the-wall radar imaging.
A noncoherent through-the-wall radar imaging system approach, based on trilateration technique, is presented. This approach involves multiple independent monostatic radar units and as such, provides flexibility in positioning the units with various stand-off distances and inter-element spacing. We demonstrate the proposed noncoherent system using simulated data. We also evaluate the performance of the noncoherent radar system when the radar positions are perturbed from their assumed values. Theoretical expressions for the bias and variance of errors in target location estimates are derived and compared with simulation results for both broadside and off-broadside targets.
