摘要
由于单个PIR构成的单节点探测视场存在大量的探测盲区,盲区所占面积相对较大,不能对目标实施有效定位,定位误差基本上达到1.5 m^2.5 m左右,基于此,提出了三角交叉定位技术研究。采用位于同一平面内的三个节点,对同样位于同一平面的目标进行交叉定位,经过实验验证,目标定位误差可以减小到1 m以内,定位精度得到了一定程度的提高,具有一定的实际应用价值。
Due to a single PIR form of single node detection field, there are a great number of blind spot detections of blind areas. The blind area is relatively large. It can＇ t implement efficiently to position on the target. The positioning error reaches about from 1.5 m to 2.5 m. Based on this, it puts forward the law triangle positioning method, uses the three nodes in the same plane and fixes the cross located on the same plane of the same goal. Through experimental verification, the target positioning error can be reduced to less than 1 m to improve the positioning accuracy of a certain level and it has certain actual application value.
