Title (EN) MONITORING DEVICE
(FR) DISPOSITIF DE SURVEILLANCE
(JA) 見守り装置
Abstract:
(EN) This monitoring device is provided with a transmission antenna (2), multiple receiving antennas (3A-3D), a selection circuit (4), an FM-CW radar unit (1), an A/D converter (7) and a signal processing unit (5). The selection circuit (4) selects one receiving antenna from the multiple receiving antennas (3A-3D). The signal processing unit (5) causes the FM-CW radar unit (1) to transmit a transmission signal or receive a receiving signal while switching the selection circuit (4) so as to obtain beat signals corresponding to each of the multiple receiving antennas (3A-3D). After a beat antenna which has been converted to a digital signal is subjected to phase correction processing depending on the corresponding receiving antenna, the signal processing unit (5) synthesizes the phase-corrected beat signals obtained by the receiving antennas (3A-3D) and detects the azimuth and distance of a monitored subject. Thus, a monitoring device with a simple configuration is provided which can identify the azimuth and position of a monitored subject.
(FR) L'invention concerne un dispositif de surveillance qui est pourvu d'une antenne d'émission (2), de multiples antennes de réception (3A-3D), d'un circuit de sélection (4), d'une unité radar FM-CW (1), d'un convertisseur A/N (7) et d'une unité de traitement de signal (5). Le circuit de sélection (4) sélectionne une antenne de réception parmi les multiples antennes de réception (3A-3D). L'unité de traitement de signal (5) amène l'unité radar FM-CW (1) à émettre un signal d'émission ou à recevoir un signal de réception tout en commutant le circuit de sélection (4) de façon à obtenir des signaux de battement correspondant à chacune des multiples antennes de réception (3A-3D). Une fois qu'une antenne de battement, qui a été convertie en signal numérique, est soumise à un traitement de correction de phase en fonction de l'antenne de réception correspondante, l'unité de traitement de signal (5) synthétise les signaux de battement à phase corrigée obtenus par les antennes de réception (3A-3D) et détecte l'azimut et la distance d'un sujet surveillé. Ainsi, l'invention concerne un dispositif de surveillance dont la configuration est simple et qui peut identifier l'azimut et l'emplacement d'un sujet surveillé.
(JA) 見守り装置は、送信アンテナ(2)と、複数の受信アンテナ(3A~3D)と、選択回路(4)と、FM-CWレーダユニット(1)と、A/D変換器(7)と、信号処理部(5)とを備える。選択回路(4)は、複数の受信アンテナ(3A~3D)から1つの受信アンテナを選択する。信号処理部(5)は、複数の受信アンテナ(3A~3D)の各々に対応するビート信号を得るように選択回路(4)を切換えながらFM-CWレーダユニット(1)に送信信号の送信と受信信号の受信を行なわせる。信号処理部(5)は、デジタル信号に変換されたビート信号に対して対応する受信アンテナに応じて位相の補正処理を行なった後に、複数の受信アンテナ(3A~3D)のそれぞれによって得られた位相補正後のビート信号を合成して見守り対象の方位と距離を検出する。これにより、簡易な構成で見守り対象の方位や位置を特定できる見守り装置を提供する。
