Modular Echo Pre-Processing Technology

Based on the research of multi-function phased array radar data processing,we developed a key technology about echo pre-processing module constructing.The paper was organized as follows: first the function of echo pre-processing was analyzed, second the implement methods of every modules were developed including data storage and application, targets' spot mearurement and compltation,coordinate transform and data fusion,clutter suppressing etc.. third the software system of echo pre-processing was developed which could be reconstructed,expanded and upgraded. The ways of this paper was the important part of our radar data processing software system , processing software system, and it improved the quality and reliability of radar software system .
