To prevent a reduction in output accuracy of a laser radar device.SOLUTION: A map data structure 110 of map data stored in a map data storage unit 11 is used in a matched filter 6 that performs processing of reducing noise in an output signal from a light receiving unit 3 of a lidar 1 comprising a light emitting unit 2 and the light receiving unit 3. Information 112 on the waveform of a reference signal used in the matched filter 6 is set to every predetermined area 111, and the matched filter 6 performs processing on the output signal based on the information 112 on the waveform of the reference signal.SELECTED DRAWING: Figure 1 【課題】レーザレーダ装置の出力精度の低下を抑えることができるようにする。【解決手段】地図データ格納部１１に格納されている地図データの地図データ構造１１０は、発光部２及び受光部３を備えるライダ１の受光部３の出力信号のノイズ低減処理を行うマッチドフィルタ６で用いられる地図データの地図データ構造１１０であって、マッチドフィルタ６で利用される基準信号の波形情報１１２が所定のエリア１１１毎に設定され、基準信号の波形情報１１２に基づいてマッチドフィルタ６が出力信号の処理をする。【選択図】図１
