噪声目标转向机动自动检测

根据观测器--目标保持匀速直线运动时目标方位随时间线性变化的一种可量测函数,研究了一种检测目标转向机动的新方法.由于该方法将目标方位随时间变化的非线性关系转换到另一空间的线性关系,这使得检测更加有效、直观,并且能够克服直接采用方位序列检测目标转向机动在特殊情况下失效的限制.最后计算机仿真计算及实测数据验证结果表明,该方法能快速、准确地检测目标的转向机动.

Automatic Detection of Noise Target Course-change Maneuvers

In this paper,we study a new method of automatic detection of target course-altering maneuvers based on a linear measurable function of bearings varying with time when the target travels on a straight line at a constant speed.Because the method uses the linear measurable function of bearings varying with time,so it is more effective than the normal method which based on bearings of the target directly,and at the same time it can overcome the limits when use the normal method in special situation.The final simulation and the real bearings data show that this method can detect the target course-altering maneuvers quickly and precisely.
