This paper introduces a high resolution imaging method, which is based on hybrid sampling of the airborne MIMO radar, combined the single snapshot of MIMO radar with the synthetic aperture of SAR. The method represents an equivalent array algorithm that the PRF of the system can be reduced dramatically to the conventional SAR, such that large unambiguity areas we can get. Numerical simulations are...
The particle swarm optimizer algorithm (PSO) is a recently developed evolutionary search technique, In order to improve the precision of range alignment in ISAR data processing, a new method is presented based on particle swarm optimizer. The range profile distance is used as fitness function in PSO searching motion parameters, which evaluate each individual based on target range profiles, in such...
The multi-input multi-output synthetic aperture radar (MIMO-SAR) is an innovative concept, which can bring high degrees of freedom for SAR system with limited transmitting/ receiving (T/R) elements. In this paper, ground moving target indication (GMTI) for MIMO-SAR is studied based on reasonable usage of the space-time equivalent samplings. Furthermore, this paper gives a deep insight of the azimuth...
