A kind of method of using imaging to measure thin wire diameter was presented.

For effective detection of foreign fibers which have almost the same shape and color as the cotton fibers, an infrared spectral imaging method based on the absorption characteristic discrimination between cotton fibers and foreign fibers was proposed.

This paper presents an imaging method of correcting range migration in frequency domain, and a method of combining the rang error correction and geometry correction,which can make the imaging efficiency better.

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.
