摘要
Abstract
Due to the effects of search modes and targets' beam scheduling, the reconnaissance systems can only intercept segment pulse trains from emitters, which is a big challenge for signal sorting. For this problem, a new method based on PRI transform spectrum coherent accumulation is proposed. PRI transform algorithm is introduced. The relationship between PRI spectrum peak value and pulse number included is given and its coherent accumulation feature is then revealed. Simulation results show that the new method can efficiently enhance PRI spectrum and is favourable to improve the detection propability.关键词
