- 電波を用いて物標を検出するレーダ装置であって、
第1パルス、並びに前記第1パルスよりも振幅及びパルス幅が大きい第2パルスを送信する送信部と、
前記送信部が送信した前記第1パルス及び前記第2パルスの物標による反射波を受信する受信部と、
前記受信部が受信した前記反射波の反射波信号に基づいて前記物標を検出する検出部と、
を備え、
前記送信部は、前記第1パルスの立ち上がり時間が前記第2パルスの立ち上がり及び立ち下がり時間よりも小さくなるよう、前記第1パルス及び前記第2パルスの波形を形成し、且つ、立ち上がり時間が互いに異なる2つの原波形信号を形成するとともに、前記2つの原波形信号をずらして掛け合わせることで前記第1パルスの波形を形成する、レーダ装置。 - 前記送信部は、立ち上がり時間が大きい方の前記原波形信号のピークにおいて前記第1パルスが有値となるよう前記2つの原波形信号を掛け合わせる、請求項1に記載のレーダ装置。
