Research on azimuth-only passive location technology of UAV carrying formation based on Newton iterative algorithm

Abstract

The problem studied in this paper is put forward on the basis of avoiding external interference and maintaining formation when UAV cluster is flying in formation. Newton iterative algorithm is used to establish multivariate nonlinear programming model. By analyzing the characteristics of passive positioning model, the sine theorem of UAV in formation is established to obtain the position of UAV in polar coordinate system. Understand the distribution of UAV, establish the nonlinear programming model, use Newton iterative algorithm, carry out the coordinate changes of UAV in the process of continuous adjustment, proofread the result and the standard position difference, more and more accurate, so as to get the final optimal strategy; Newton iteration method in classical iterative algorithm was used to sort out the location model of passive signal receiving UAV.
