无线测向定位算法及实现系统

随着无线通信技术和卫星导航技术的发展,无源定位技术成为电子对抗领域的热点问题。主要对无源定位技术方法进行了分析,重点分析了无源测向定位相关理论,并提出了测向定位与几何联立的新算法。通过地面探测系统进行该算法的验证,得到目标辐射源的绝对误差在经度上为1.16°×10~(-4),纬度上为1.04°×10~(-4),其相对误差在经度上为9.77×10~(-7),纬度上为3.23×10~(-6)。实际误差距离通过MATLAB计算得出为26.67 m。通过实验验证与结果分析,对于不定时目标辐射源,该算法具有很好的有效性与可行性。

Wireless orientation and location algorithm and its implementation system

With the development of wireless communication technology and satellite navigation technology,passive positioning technology has become a hot topic in the field of electronic countermeasures. This paper mainly analyzes the passive positioning technology,focuses on the analysis of the theory of passive direction finding and proposes the algorithm of orientation and geometric union. Through the ground detection system to verify the algorithm,the absolute error of the target radiation source is 1.16°×10 -4on the longitude and 1. 104×10 -4on the latitude,the relative error is 9.77×10 -7on the longitude and 3.23×10 -6on the latitude. The actual error distance is 26.67 m calculated by MATLAB. Through experimental verification and result analysis,the algorithm is effective and feasible for non-timed target radiation sources.
