How to reduce the influences of the location error of seismic station network and some other factors on the deviation of macroseismic and seismic epicentre, in this rapid service system of earthquake loss estimation, is the important condition of increasing the rationality of loss estimation results
在震害預測快速服務平臺中，如何減少由於地震臺網定位誤差以及其它一些因素所造成實際的宏觀震中與定位震中偏離的影響，是提高震害快速估計結果合理性的重要條件。 -
The emitter location methods commonly include : angle of arrival ( aoa ) measurement, time - difference - of - arrival ( tdoa ) measurement and aoa together with tdoa measurement. this paper derive some important techniques and theories bearing upon passive location in this field. three kinds of passive location algorithm in three - dimensional ( 3 - d ) space are deduced based on that of 2 - d space. at the same time each performance is analyzed, each graph of geometric dilution of precession ( gdop ) is emulated for different station position, different measurement error, and different target height. accordingly some valuable academic and emulational results are obtained by myself, which will provide researches in this field with definite technical refrence. at the end of this paper, the passive location method of jtids ( joint tactical distribution systems ) is discussed, which is expected to enforce the tactical performance of jtids in the intending development
本文汲取了該領域有關被動定位的重要技術和理論，在二維平面無源定位演算法的基礎上推導出了三維空間內的三種無源定位演算法，並對各自的定位性能進行了理論分析和計算機模擬，模擬出不同的布站、不同的測量誤差以及不同輻射源高度的情況下，三種定位方法各自對應的定位精度（ gdop ）分布圖，同時對各自的定位性能進行了改進處理，得出了一些有價值的理論和模擬實驗結果，這些結論可為今後在此領域的研究提供一定的技術參考。
