干扰目标双站测向定位模型

The Interpolation Synch Algorithm in Direction Measurement Locating Model of Jamming Target

针对干扰目标的空间定位问题,推导出一种双站测向定位的数学模型。提出了测向定位的插值同步计算问题,对水平等速直线飞行目标的航迹进行研究,分析了目标高低角和方位角的变化规律,采用一种有效的有理插值——倒一次插值,作为测向插值同步计算函数,使两雷达站送来的数据在时间上具有同一性,提高了定位精度,具有一定的工程应用价值。

Aiming at jamming target space locating, this paper deduces a mathematic model of direction measurement based on two radars, puts forward the issue of interpolation synch calculation, studies the track of level fixed - velocity straight target, analyzes thechange law of pitching angle and azimuth angle and establishes a proper rational interpolation - simple reciprocal interpolation as the synch calculation function. In this way, the data sent from the two radars are identical in time, and the locating precision is improved. The model established in this paper is of engineering application value.
