基于持续到达信号强度的辐射源定位方法
Emitter location method based on continuous strength of arrival
摘要
Abstract
In order to improve the location accuracy of emitter sources,a location method based on continuously arriving signal strength was proposed.More than five monitoring points needs to be randomly distributed in the area to continuously monitor the electromagnetic wave signal strength of this frequency,and according to the signal intensity and duration monitored at each measuring point,and the relationship between the transmission distance and loss of electromagnetic waves in free space,the three-dimensional coordinates of the emitter source were calculated by using the method of multiple linear regression.The results show that the main factors of target success rate and accuracy decrease are the position error of the monitoring point and the monitoring time error of each monitoring point.The measurement error of the monitoring point has little influence on the location success rate and accuracy.The increasing number of monitoring points can significantly improve the location success rate and accuracy,but it also increases the cost;In the case of a small number of monitoring points,increasing the continuous monitoring time can effectively offset the impact of position error and time error on the location success rate and accuracy,and it can achieve a better effect than increasing the number of measuring points.The method can greatly improve the location success rate and accuracy at the expense of reducing the real-time performance without increasing the hardware cost,and it can be applied to electromagnetic emitter source location scenarios with low real-time requirements.关键词
