Abstract
(EN)
This electronic device detects an object that reflects a transmission wave on the basis of a transmission signal transmitted as the transmission wave from a transmission antenna and a reception signal received from a reception antenna as a reflected wave of the transmission wave. The electronic device determines that an object has been detected, when a peak in a result obtained by performing a Fourier transform process on a beat signal generated on the basis of the transmission signal and the reception signal is equal to or greater than a predetermined threshold. The electronic device sets the predetermined threshold on the basis of an object detection probability.
(FR)
Ce dispositif électronique détecte un objet qui réfléchit une onde de transmission sur la base d'un signal de transmission envoyé en tant qu'onde de transmission à partir d'une antenne de transmission et d'un signal de réception reçu d'une antenne de réception en tant qu'onde réfléchie de l'onde de transmission. Le dispositif électronique détermine qu'un objet a été détecté, lorsqu'un pic dans un résultat obtenu par réalisation d'un processus de transformation de Fourier sur un signal de battement généré sur la base du signal de transmission et du signal de réception est supérieur ou égal à un seuil prédéterminé. Le dispositif électronique règle le seuil prédéterminé sur la base d'une probabilité de détection d'objet.

電子機器は、送信アンテナから送信波として送信される送信信号、及び、送信波が反射された反射波として受信アンテナから受信される受信信号に基づいて、送信波を反射する対象物を検出する。電子機器は、送信信号及び受信信号に基づいて生成されるビート信号にフーリエ変換処理を行った結果におけるピークが所定の閾値以上となる場合に、対象物を検出したと判定する。電子機器は、所定の閾値を、物体検出確率に基づいて設定する。
