| The invention relates to a method for generating target-marking directional tracks for a plurality of sound-emitting targets in a sea area directed by a plurality of sensors, each sensor providing a sensor track made of sequential bearings for each found and tracked target. In order to reduce the plurality of directional tracks to only as many target-marking directional tracks as targets found by the totality of sensors, and in order to correctly assign track segments between which gaps in time occur, sensor tracks of a plurality of sensors that are derived from a common target are consolidated into contact tracks-starting from the sensor tracks of the most accurate sensor-to form a track-to-track fusion, and contact tracks that are offset in time are checked for the probability of them belonging together. Contacts tracks that are offset in time and have a high probability of belonging together are associated with each other and designated as uninterrupted target tracks. | ||||||

| PROBLEM TO BE SOLVED: To make it possible to estimate the sound source position that has been difficult for the conventional system using a small number of microphones, so as to improve the conventional estimating accuracy of the sound source position. SOLUTION: It is made possible to estimate the sound source position by forming a reflection surface RS as a enveloping surface of spheroid using the location of a collection means and the sound source location as the focal points, by generating main reflected waves with the amount of delay corresponding to the sound source location, and by inspecting the amount of delay between the direct wave and the reflected wave so as to acquire the sound source location and to make estimable the location.

| (57)【要約】 多次元音響データ処理および表示システムは、音響データを三次元行列の形式に整理する。 その三次元行列は、特異値分解を用いて、特異ベクトルと特異値に圧縮される（８１）。 履歴データベースが作成され、保守され、さらに、三次元データと連結される。 このデータベースは、残響や雑音を減少させ、そのデータ中のより弱い特徴や特性を高品位化することができる。 そのデータは一旦圧縮されると、効率的に分析される。 それらの特異ベクトルは、それらの特異値か、他の判定基準を基にして、１つかそれ以上のグループに分割される。 特異ベクトルのグループのそれぞれの範囲内で、特異値を変更することによって、圧縮データ要素のある部分は、高品位化されるか、縮小される。 選択された特異ベクトルは、次の高品位化、検出、分離、特徴の抽出および分類のための他の技術によって、さらに処理される。 次に、その圧縮され、かつ高品位化されたデータは、表示（８４）のために、三次元形式に伸長される（８３）。 | ||||||

| PURPOSE: To suppress an interference signal based on the information related to the directivity by obtaining a wide band estimation value for the direction of a sound source based on a narrow band estimation value obtained from a direction estimator provided for a data processing unit. CONSTITUTION: A beam to be scanned from a sound sensor array 1 is amplified, filtered and A/D converted 2 to produce a signal S(K) which is then delayed to form 3 a signal S(ϕ i) representative of a sound signal received in the direction ϕ i. It is then subjected to frequency analysis 4 with high resolution and a selected signal S(ϕ i, f j) is delivered at a repetitive frequency of 0.2-1.2Hz to a data processor 5. A direction estimator 6 in the processor 5 delivers a wide band estimation value QBB of the direction Q of a sound source, a track and a confidence factor CF to a general purpose computer 9 based on a narrow band estimation value in order to estimate the direction ϕ ie of the sound source. Furthermore, a correction signal S'(ϕ i, f j) obtained by removing 7 a background signal from the signal S(ϕ i, f j) of repetitive frequency is delivered to a detector 8 where a signal having frequency f' j higher than a threshold value is selected and delivered to the estimator 6 as information for selecting an appropriate signal and to a display 10.
