I. Introduction
Information security has attracted more attention, especially civil aviation security. Parameter estimation is an attractive topic in civil aviation security. Multiple-input multiple-output (MIMO) radar has attracted wide attention from scholars due to its many advantages. Target parameter estimation and localization are a hot issue in radar signal processing[1]-[10]. Scholars have proposed many methods of parameter estimation. The literatures [3]-[5] study the estimation methods of Doppler frequency and time delay based on various time-frequency distributions. The literature [10] proposes a joint estimation algorithm of Doppler frequency, DOD and DOA based on parallel factor analysis, and the estimated parameters are automatically paired without the additional pairing method.
