Abstract
Fresnel telescopy full-aperture synthesized imaging ladar is a new high resolution active laser imaging technique. In the operational mode with moving target by beam scanning, spatial distributions of the complex data of the returned signals are not regular or uniform. In order to use fast Fourier transform (FFT) algorithm in signal processing, algorithm for Fresnel telescopy imaging system should include resampling interpolation step to change sampling data into uniform and quadratic spatial distribution. We choose suitable resampling interpolation algorithm for Fresnel telescopy, and get computer simulation of area target. The work is found to have substantial practical value and offers significant practical benefit for high resolution imaging in Fresnel telescopy imaging ladar.
