The SAR imaging algorithm of moving spot targets in the background of ground clutters;

Improved bistatic SAR imaging algorithm based on numerically computed transfer functions;

Based on the characteristics of high-speed carrier,short imaging disposing time and nonlinear moving of the high squint missileborne SAR imaging,deduces a series of parameters that describing the varying range and phase of target echoes under the condition of known motion error,and an RD imaging algorithm based on motion compensation is proposed.

A high resolution spotlight SAR image formation algorithm free of any approximations is proposed to overcome the problems of geometric distortion and limited scene size resulting from RVP which is a direct consequence of the signal dechirp-on-receive approach for spotlight data collection, and from neglecting range curvature in PFA processing commonly adopted in spotlight SAR system.

High-resolution air-borne Synthetic Aperture Radar (SAR) image formation algorithms and its motion compensation are the main research content of this paper.

An improved range Doppler imaging algorithm applying sub-aperture motion compensation is used in the system,which features less operation and fine compensation.
