高仰角弧段雷达跟踪不稳定因素分析

现在多数雷达采用的是方位-俯仰型天线座。在雷达自跟踪时方位支路原理上要加入正割补偿,且随着仰角的提高补偿系数会逐渐增大。跟踪系统加入正割补偿后将对高仰角弧段雷达的跟踪性能产生影响。对高仰角弧段时影响雷达稳定跟踪的因素作了全面分析,以实际雷达跟踪数据说明在不同情况下,主要影响因素也不相同,并制定了高仰角弧段雷达的跟踪策略。

The Indetermination FACTOR Analysis of High Elevation arc Segment Sadar TRACKING

Now the majority of radars adopt the azimuth-EL type aerial mount, according to the azimuth of principle in the radar auto tracking needs to join secant offset, and the offset coefficient will enlarge gradually along with the exaltation of elevation. Being adding the offset,the tracking system will effect on the performance of trail radar in high elevation arc segment.The author analyzed the factor that effected the radar track steadily completely, with actual radar tracking data, explained the main impact factor was different either under the different condition, and drew up the trail of strategy of high elevation arc segment radar.
