基于变化方位角最小二乘估计的电子侦察机无源定位技术研究

Research into Passive Location Technology of Electronic Reconnaissance Aircraft Based on Variable Azimuth Least Square Estimation

随着电子战技术的不断发展,在复杂的电磁环境环境中,以雷达为代表的有源定位技术受到越来越严重的威胁。而无源定位技术,由于其本身不发射电磁波,具有隐蔽性好、作用距离远的特点,被广泛应用于电子侦察机领域。基于变化方位角最小二乘估计对电子侦察机无源定位的战术决策进行寻优仿真。通过大量的仿真数据,分析了电子侦察机转向角度对定位结果的影响,对于提高电子侦察机的定位效能具有较高的应用价值。

With the continuous development of electronic warfare technology,in the complex electromagnetic environment,active location technology represented by radar is threatened more and more seriously.Passive location technology is widely used in the field of electronic reconnaissance aircraft,because it does not emit electromagnetic waves,has the features of good concealment and far operation range.This paper optimizes and simulates the tactical decision of passive location for electronic reconnaissance aircraft based on the variable azimuth least square estimation,analyzes the influence of steering angle of electronic reconnaissance aircraft on the location results through a lot of simulation data,which has upper application value to improve the location efficiency of electronic reconnaissance aircraft.
