摘要

本文提出了一种利用单一地面传感器对空中主动目标进行三维定位的方法。该方法利用直接从空中目标接收到的信号与从地面已知位置的一些大型辅助地面目标(伪传感器)反射后接收到的信号到达的时间和频率差。由于主传感器和伪传感器的地面特性,用传统方法求解目标高度是不可能的。该方法采用目标运动分析方法,以较低的计算复杂度和可接受的精度获得目标的位置和高度。仿真结果表明,在伪传感器数量有限且计算复杂度较低的情况下,该方法在确定目标三维位置方面具有良好的精度。

Three-Dimensional Localization of Active Aerial Targets Using a Single Terrestrial Receiver Site
This paper proposes a method for the three-dimensional localization of an active aerial target by a single ground based sensor. The proposed method employs the time and frequency differences of arrival of the signal received directly from the aerial target and the signals received after being reflected from some large auxiliary terrestrial targets (pseudo-sensors) with known positions on the ground. Due to the terrestrial nature of the main and the pseudo sensors, it is impossible to solve for the target's altitude using traditional methods. The proposed method employs target motion analysis to obtain target position including its altitude with acceptable accuracy and low computational complexity. Presented simulations confirm acceptable accuracy of the proposed method in determining three dimensional position of the target despite limited number of the pseudo sensors and its low computational complexity.
