Faz Farkı Türev Değişimiyle Konum Bulma için Yeni Bir Kapalı Form Çözüm

In electronic warfare (EW) systems, change in rate of phase difference (CRPD) measurements can be used for source localization. The CRPD localization problem is non-convex and non-linear, therefore, it is challenging. In this paper, a closed form solution is developed for the scenario in which the EW system is located at a flying-jet and the target is stationary. The proposed approach utilizes the flight geometry and provides a new linear model to locate the target using the least-squares (LS) approach. In the numerical simulations, we observe that the proposed method outperforms existing LS methods and it reaches the performance of the maximum-likelihood approaches if the antenna scan period of the target is low.
