摘要
Abstract
In conventional PD radar, when the coherent accumulation time is long, or when signal bandwideth is wide and the target velocity is high, the echo may occur the migration through resolution cell. In this case, the property of radar to detect targets may be affected. Keystone transform is the common method to cowect the migration through resolution cell. Three habitually used methods to implement Keystone transform are studied. The algorithm's validity is confirmed by simulation analysis. The algorithm with low complexity was found It has a certain conferece significance to the engineering implementation.关键词
