( 5 ) mfpic ( matched field postbeamformer interference canceller ) is proposed to cancel tow ship ' s noise. the advantage of mfpic is that it can be used to cancel the tow ship ' s noise for all arrival directions. furthermore, this new approach can be used to detect weak target, which has the same bearing angle of a strong interference
（ 5 ）將平面波波束形成后干擾抵消與匹配場處理技術進行有機結合，探索性地提出了拖線陣聲納本艦干擾的匹配場抵消方法和匹配場處理后的干擾抵消方法，為本艦多途干擾抵消、水面強干擾抑制和水下弱目標檢測提供了新的技術途徑。 -
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。
