Title (EN) MOVING BODY DETECTION SYSTEM
(FR) SYSTÈME DE DÉTECTION DE CORPS MOBILE
(JA) 移動体検知システム
Abstract:
(EN) The purpose of the present invention is to provide a moving body detection system that suppresses transmitted wave or reflected wave interference between radars when a plurality of radars are operating independently. The present invention is provided with: a first radar having a first transmission unit for generating first electromagnetic waves for irradiation that are electromagnetic waves having a first-polarization-direction component and a first reception unit for receiving electromagnetic waves having the first-polarization-direction component; and a second radar having a second transmission unit for generating second electromagnetic waves for irradiation that are electromagnetic waves having a second-polarization-direction component and a second reception unit for receiving electromagnetic waves having the second-polarization-direction component. Disposing the first radar and second radar along a travel path so that the polarization directions of the respective irradiated waves or reflected waves of the first radar and second radar are different results in the suppression of interference between the radars when the radars are operating independently.
(FR) La présente invention a pour objet de fournir un système de détection de corps mobile qui supprime une interférence d'onde transmise ou d'onde réfléchie entre des radars lorsqu'une pluralité de radars fonctionnent de façon indépendante. La présente invention comprend : un premier radar ayant une première unité de transmission destinée à générer des premières ondes électromagnétiques pour une irradiation qui sont des ondes électromagnétiques ayant une composante de première direction de polarisation et une première unité de réception destinée à recevoir des ondes électromagnétiques ayant la composante de première direction de polarisation ; et un second radar ayant une seconde unité de transmission destinée à générer des secondes ondes électromagnétiques pour une irradiation qui sont des ondes électromagnétiques ayant une composante de seconde direction de polarisation et une seconde unité de réception destinée à recevoir des ondes électromagnétiques ayant la composante de seconde direction de polarisation. La présente invention porte sur la disposition du premier radar et du second radar le long d'un trajet de déplacement de telle sorte que les directions de polarisation des ondes irradiées respectives ou des ondes réfléchies respectives du premier radar et du second radar soient des résultats différents dans la suppression d'interférence entre les radars lorsque les radars fonctionnent de manière indépendante.
(JA) 複数のレーダが独立に動作しながら、レーダ間の送信波または反射波の干渉を抑制する移動体検知システムを提供することを目的とする。本発明では、第一の偏波方向の成分を有する電磁波である第一の照射用電磁波を発生する第一の送信部と、前記第一の偏波方向の成分を有する電磁波を受信する第一の受信部とを備えた第一のレーダと、第二の偏波方向の成分を有する電磁波である第二の照射用電磁波を発生する第二の送信部と、前記第二の偏波方向の成分を有する電磁波を受信する第二の受信部とを備えた第二のレーダとを備え、走行路に沿って前記第一のレーダと前記第二のレーダをそれぞれのレーダの照射波または反射波の偏波方向が異なるように設置することで、前記レーダが独立に動作しながらレーダ間の干渉を抑制する。
