Title (EN) CLUTTER ELIMINATION AND MULTI-TARGET TRACKING METHOD FOR RADAR SYSTEM

Abstract: front page image
(EN) The present invention relates to a clutter elimination and multi-target tracking method for a radar system, comprising the steps of: (a) allowing a transmitting/receiving unit of the radar system to transmit a radar signal to surroundings and receive a signal reflected from a target; (b) allowing a control unit to generate radar detection information by using the received radar signal; (c) eliminating clutter information from the radar detection information; (d) checking whether target tracking prediction information, which uses the radar detection information from which the clutter information is eliminated, and actual detection information are matched; and (e) updating a tracking history by using all of the matched and unmatched tracking information of the checking result in step (d), thereby using multi-target detection information so as to eliminate clutter, tracking the same target, reducing a target false alarm rate through an undetected target estimation, and improving the accuracy of a target detection rate and measurement information.
(FR) La présente invention concerne un procédé d'élimination d'encombrement et de suivi multi-cible pour un système radar, comprenant les étapes consistant à : (a) permettre à une unité d'émission/réception du système radar de transmettre un signal radar à l'environnement et de recevoir un signal réfléchi par une cible ; (b) permettre à une unité de commande de générer des informations de détection radar à l'aide du signal radar reçu ; (c) éliminer des informations d'encombrement à partir des informations de détection radar ; (d) vérifier si des informations de prédiction de suivi de cible, qui utilisent les informations de détection radar à partir desquelles les informations d'encombrement sont éliminées, et des informations de détection réelles sont mises en correspondance ; et (e) mettre à jour un historique de suivi en utilisant toutes les informations de suivi mises en correspondance et non mises en correspondance du résultat de vérification de l'étape (d), ce qui permet d'utiliser des informations de détection multi-cible afin d'éliminer l'encombrement, de suivre la même cible, de réduire un taux de fausse alarme cible par l'intermédiaire d'une estimation de cible non détectée, et d'améliorer la précision d'un taux de détection de cible et d'informations de mesure.
(KO) 레이더 시스템의 클러터 제거 및 다중 표적 추적방법에 관한 것으로, (a) 레이더 시스템의 송수신부에서 주변으로 레이더 신호를 송신하고, 표적에서 반사되는 신호를 수신하는 단계, (b) 제어부에서 수신된 레이더 신호를 이용해서 레이더 검지정보를 생성하는 단계, (c) 상기 레이더 검지정보에서 클러터 정보를 제거하는 단계, (d) 상기 클러터 정보가 제거된 레이더 검지정보를 이용한 표적 추적 예측 정보와 실제 검출정보가 매칭되는지 검사하는 단계 및 (e) 상기 (d)단계의 검사결과 매칭 및 언매칭된 모든 추적 정보를 이용해서 추적 히스토리를 갱신하는 단계를 포함하는 구성을 마련하여, 다중 표적 검출정보를 이용해서 클러터를 제거하고, 동일 표적을 추적하며, 미탐지 표적 추정을 통하여 표적 오경보율을 감소시키고, 표적 탐지율과 측정정보의 정확도를 향상시킬 수 있다.
