摘要
运动单站无源定位具有灵活性高、机动性好、无需信息同步和交换的特点,可满足区域性突发干扰监测的需求。利用运动的单站自身位置不断转移,从而使得干扰源相对方向不断变化,采用最小二乘的方法对移动的观测源实时接收到的测向数据进行处理,来确定固定干扰源的位置。仿真实验表明:该方法能够在观测源运动的情况下实现固定干扰源的定位,且具有较好的定位精度。
The moving single observer passive localization has such characteristics as high flexibility and high mobility,and it has no need of information synchronization and information exchange,so it can meet the needs of regional burst interference monitoring. In this paper,the relative orientation of the source of interference can be received by using a continuous moving single observer. Then the direction finding data received in real time from the moving single observer is analyzed by using the least squares estimation to deter-mine the location of fixed interference source. The simulation results show that this method can implement the localization of fixed inter-ference source when the observer is moving,and guarantee good positioning accuracy.
