Abstract VHF radar has unique advantage in anti-stealth and resisting anti-radiation missile. It plays an important role in modern antiaircraft system. However, the multipath signal often brings difficulties to the altitude measurement of VHF radar. Combining with the characteristics of VHF array radar and array multipath signal model, this paper summarizes and concludes three VHF radar height measurement methods based on the traditional Maximum Likelihood (ML) algorithm: the altitude measurement method based on the temporal-spatial sequential ML algorithm; the altitude measurement method based on the improved temporal-spatial sequential ML algorithm; the altitude measurement method based on the Refined Maximum Likelihood (RML) algorithm. This paper presents the theoretical performance analysis of these methods, the relationship between three methods, and the results of computer simulation experiments. Finally some meaningful conclusions are given.
