Abstract:

Lonttime coherent integration is used for target detect will result in rangecellcrossing。So,In signal process of Radar,an effective way is to employ Keystone transform to slove the problem.But the reality of the Keystone transform is very difficulty,because it need mass of compute work.Base on FPGA,this paper take a method for reality the transform.After the simulation and analysis the Keystone transform,give the comput process of the simplify method,compute work has dropped off sharply. After the design code is done,the result is verify this theory,It indicatethe all condition is meet,and the theory can be used in engineering.

Key words: signal process of radar, long time coherent integration, range cell crossing, Keystone transform, FPGA
