双机海上无源定位算法与路径的数学模型研究

Research on Algorithm and Mathematical Model of Dual-Robot Passive Location

摘要: 对辐射源进行准确、迅速定位，是侦察、预警、监视和补给等应用领域中的一个重要问题。而无人机由于其目标小、成本低的优势，在现实实际应用的信息获取中扮演了重要角色。利用无人机群对海上固定目标进行无源精确定位，可以大大提升对海上目标的侦查、监视以及补给等能力。双机时差频差定位体制由于其结构简单、定位精度高而备受关注。本文以时差、频差方程为基础，建立估计目标位置的定位模型，采用粒子群求解定位模型，并证明其可行性，为实际的相关问题提供了参考。

Abstract: Accurate and rapid location of radiation sources is an important problem in the application fields of reconnaissance, early warming, monitoring and replenishment. Due to its small target and low cost, UAV plays an important role in information acquisition in practical applications. Using UAV group to passively locate fixed targets at sea can greatly improve the ability of reconnaissance, surveillance and replenishment of targets at sea. Duel-machine time-difference-frequency-difference positioning system has attracted much attention because of its simple structure and high positioning accuracy. In this paper, based on the equation of time difference and frequency difference, a positioning mod-el is established to estimate the target position, and a search method is used to solve the positioning model.
