PROBLEM TO BE SOLVED: To provide a radar signal processor detecting a specific target located in a short range of a radar device mounted on a vehicle and a radar device having the radar signal processor incorporated therein, which can surely detect an object that moves at low speed and an object that stays still and slightly moves.SOLUTION: A radar signal processor processing a radar signal arriving at a radar mounted on a vehicle, and detecting a target which is located in a prescribed short range and is displaceable at slow speed, and with which the vehicle is possible to come in contact at a speed higher than a prescribed speed, comprises: period specification means that specifies a period for which the speed of the vehicle can be accelerated at the speed equal to or higher than the prescribed speed; and target identification means that identifies presence of the target as a distribution of a Doppler component of the radar signal within the short range during the period.SELECTED DRAWING: Figure 1

    【課題】 この発明は、車両に搭載されたレーダ装置の近レンジ内に位置する特定の目標を検知するレーダ信号処理装置と、そのレーダ信号処理装置が組み込まれたレーダ装置とに関し、低速で移動する対象物や静止していてわずかな動きのある対象物を、確実に検出できる。【解決手段】 車両に搭載されたレーダに到来したレーダ信号を処理し、規定の近レンジ内に位置し、かつ微速で変位し得ると共に、前記車両が規定の速度以上で接触し得る目標を検知するレーダ信号処理装置であって、前記車両の速度が前記規定の速度以上に加速され得る期間を特定する期間特定手段と、前記期間に、前記近レンジ内における前記レーダ信号のドップラ成分の分布として、前記目標の存在を識別する目標識別手段とを備える。【選択図】 図1
