摘 要：
A data acquisition and analysis system for the scanning entomological radar images developed by the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences was introduced. In this system, the VGA signal from the radar's digital PPI display is captured as a single-frame or a multiple-frame bitmap images. The images were processed and the radar parameters were auto recognized by the analysis software. Then the migration parameters for the over flying population-density, speed, direction, flux, collective orientation and their variances were estimated. This computer based image-analysis technique had proved effective in recent observations.
