前記レーダ信号処理部は、静止した前記物標に係る反射波信号のレベルに基づいて演算された積算値とレーダ装置の異常判定のための閾値とから、該レーダ装置の異常を判定する感度低下判定部を有するレーダ装置。 A radar signal processing unit that detects a target based on a reflected wave signal obtained by receiving a reflected wave of a transmitted beam reflected from the target;
The radar signal processing unit reduces sensitivity of determining an abnormality of the radar device from an integrated value calculated based on a level of a reflected wave signal related to the stationary target and a threshold value for determining the abnormality of the radar device. A radar apparatus having a determination unit.
前記感度低下判定部は、前記各ビームにおける前記反射波信号のレベルの最大値と最小値との差分値を所定時間積算した積算値と、予め設定された前記閾値とを比較し、該積算値が該閾値以下であるときに、前記レーダ装置に異常があると判定することを特徴とする請求項１に記載のレーダ装置。 The radar signal processing unit detects the target on the basis of a reflected wave signal obtained by receiving a reflected wave in which a plurality of transmitted beams are reflected from the target;
The sensitivity decrease determination unit compares an integrated value obtained by integrating a difference value between a maximum value and a minimum value of the level of the reflected wave signal in each beam for a predetermined time with the preset threshold value, and calculates the integrated value. The radar apparatus according to claim 1, wherein when the value is equal to or less than the threshold, it is determined that the radar apparatus is abnormal.
