Space–time adaptive processing (STAP) is usually adopted in airborne and spaceborne radars for clutter suppression and slow moving target detection. However, for traditional sample covariance matrix inversion algorithm, there are usually not enough independent and identically distributed secondary samples to achieve a satisfactory performance. The diagonal loading methods are usually utilised to solve...
This paper studies the impacts of ionospheric scintillation on geosynchronous SAR (GEO SAR). A phase screen model is used to simulate the influence of ionospheric scintillation on GEO SAR. In this model, the ionospheric scintillation status (i.e. the thin phase screen) is generated by employing the Rino equation and the climatological paramters (such as CkL, p and L0). When wave passes through the...
This paper studies echo simulations of spaceborne millimeter-wave cloud profiling radar (CPR). It employs the cloud reflectivity data from 94GHz CloudSat CPR to construct the real scene and the cloud scattering model. In the simulation, the radar model, the relative motion model, the cloud scattering model, the scattering particle motion model and the atmospheric propagation and attenuation model...
