Estimating In-pulse Characteristics of Radar Signal Based on Multi-index

There are many in-pulse characteristic parameters which can be used for sorting and recognizing radar emitter signals, and they are estimated by right rate usually. For the current electromagnetism environment is composed of compression, complexity and levity, it is not reasonable to estimate the performance of the characteristic parameters only by right rate. Complexity, separability and stability are proposed in this paper to review the performance of radar signal sorting and recognition, and a novel method of estimating characteristic parameters of radar emitter signal is designed. By simulation and analyse, this novel method can estimate the performance of characteristic parameters roundly and accurately, and choose the best parameter for different applied demands.
