Abstract:
Passive bistatic radar is considered. It includes an illumination source and two antennas. The reference antenna receives a direct signal from an illumination source and the target antenna receives a mix of the signals scattered by mobile objects. The problem of amplitudes, delays and Doppler shifts estimation of scattered signals is formulated as a residual minimization problem of the overdetermined system of linear algebraic equations. The additional condition to unknown amplitudes provides sparsity of searched signals amplitudes in delay - Dopler shift coordinates. The variational method is used for the solution of this problem. The resulting algorithm is shown to be effective in typical simulated scenarios with a six moving craft. For practical algorithm realization it is necessary use the multicore computer and code parallelization.
