摘要
Abstract
In order to address the problem of range-measure error in linear frequency modulated(LFM)radar systems under the condition of high and variable range-Doppler coupling coefficients,this paper is based on the stochastic process ranging principle constructed by stochastic differential equation theory to propose a range-mea-sure correction method,then uses the predicted value of radial velocity to modify the measured range by selecting the maximum coupling coefficient,and finally presents the revised oblique distance estimation model.Simulation results show that compared with the existing methods,the proposed correction method has better performance in range estimation during waveform switching.关键词
