基于频率微分属性的跳频信号参数估计
Parameter Estimation of Frequency Hopping Signals Based on Frequency Differential Property
摘要
Abstract
A method for the characteristic parameter estimation of the frequency-hopping signals jump cycle, transition time, and frequency was described based on the differential nature of frequency-hopping. Compared to the traditional maximum smoothed pseudo Wigner-Ville distribution, the proposed method has high accuracy of parameter estimation and reliability of detection at transition time. The validation of the proposed method was demonstrated in the simulation results and performance analysis.关键词
