Abstract:
(EN) A radar signal processing device is provided with: a center cell calculation part (5) for calculating, out of a plurality of resolution cells in a first range-Doppler map and a second range-Doppler map, each resolution cell associated with a position and speed at first receipt time and second receipt time as a first center cell and a second center cell, said position and time being predicted by a movement prediction part (3); and a likelihood calculation part (6) for calculating each likelihood between each of the resolution cells in a first area including the first center cell and each of the resolution cells in a second area including the second center cell. A signal addition part (7) selects at least one or more combinations from combinations of the resolution cells in the first area and resolution cells in the second area on the basis of each of the likelihoods calculated by the likelihood calculation part (6), and adds together signals included in the resolution cells pertaining to the selected combinations.
(FR) La présente invention concerne un dispositif de traitement de signal radar qui est pourvu de : une partie de calcul de cellule centrale (5) pour calculer, parmi une pluralité de cellules de résolution dans une première carte de portée Doppler et une deuxième carte de portée Doppler, chaque cellule de résolution associée à une position et à une vitesse à un premier temps de réception et à un deuxième temps de réception en tant que première cellule centrale et deuxième cellule centrale, ladite position et le temps étant prédits par une partie de prédiction de mouvement (3) ; et une partie de calcul de probabilité (6) pour calculer chaque probabilité entre chacune des cellules de résolution dans une première zone comprenant la première cellule centrale et chacune des cellules de résolution dans une deuxième zone comprenant la deuxième cellule centrale. Une partie d’addition de signal (7) sélectionne au moins une ou plusieurs combinaisons parmi des combinaisons des cellules de résolution dans la première zone et des cellules de résolution dans la deuxième zone sur la base de chacune des probabilités calculées par la partie de calcul de probabilité (6), et additionne conjointement des signaux inclus dans les cellules de résolution appartenant aux combinaisons sélectionnées.
(JA) 第1及び第2のレンジドップラマップにおける複数の分解能セルの中で、運動予測部(3)により予測された第1及び第2の受信時刻での位置及び速度に対応する分解能セルのそれぞれを第1及び第2の中心セルとして算出する中心セル算出部(5)と、第1の中心セルを含む第1の領域内の各々の分解能セルと、第2の中心セルを含む第2の領域内の各々の分解能セルとの間の尤度をそれぞれ算出する尤度算出部(6)とを設け、信号加算部(7)が、尤度算出部(6)によりそれぞれ算出された尤度に基づいて、第1の領域内の各々の分解能セルと第2の領域内の各々の分解能セルとの組み合わせの中から、少なくとも1つ以上の組み合わせを選択し、選択した組み合わせに係る分解能セルに含まれている信号同士を加算する。
