【摘要】 首先分析了对固定辐射源进行定位的2种模型:利用测角信息对固定辐射源的单站无源定位;利用角度及其变化率信息对固定辐射源的单站无源定位。分别对这2种定位方法进行分析,并通过推广卡尔曼滤波(EKF)算法对上述定位算法进行比较,加入角度变化率不但可以对目标瞬时定位,而且可以实现比只测向定位更高的定位精度。更多还原

【Abstract】 This paper first gives two models of location of a fixed emitter,model 1 is single station passive location of a fixed emitter with angel measuring information,model 2 is single station passive location of a fixed emitter with the angel and its,then analyzes and compares the two methods by Extended Kalman Filtering,finally concludes that the location algorithm of angel measuring information and its variable rate not only can achieve instant location for a fixed emitter,but also can get faster and more precise location result than that of location only by direction finding.更多还原
