Generation of point scatterer models using PTD/SBR technique

In radar scattering problems, a target can be represented by a finite number of discrete point scatterers, each of which produces a scattered wave of specified amplitude and phase. This is often called the point scatterer model and these point scatterers are often called scattering centers. This model was first used to analyze the radar glint and is recently implemented in the real-time, hardware-in-the-loop (HWIL) simulation. There were two ways to assign the position, the amplitude and the phase of each scattering center. The first is to assign their statistics which can be used to develop statistical models for RCS or glint. The second is to get the inverse synthetic aperture radar (ISAR) images from measurement or simulation data and process the images to generate the point scatterers. A deterministic method which does not need the ISAR imaging is proposed in this paper. It is believed to be useful for simulation purposes.
