Abstract:
Considering the dependence of the azimuth resolution on the reconstruction angle and the azimuth resolution deterioration caused by aperture loss using the traditional subaperture procession in the case of a large reconstruction angle the for helicopterborne rotating synthetic aperture radar (ROSAR), a novel echo model is established using a higher order range model for ROSAR, and the twodimensional point target spectrum is derived by the series reversion. Based on that, a novel high resolution imaging algorithm is proposed for helicopterborne ROASR, besides the parameters selection and analysis of performances is presented. Finally, the accuracy and validity of the proposed algorithm is demonstrated through simulation results.
