DEVICE, PROGRAM, AND METHOD FOR PROCESSING RADAR RECEPTION SIGNALS

To prevent the positional deviation on a display of radar reception signal data accompanying the change in the azimuth direction of observation in one time of RHI observation in a radar for performing the electronic scanning in the elevation direction while performing the mechanical scanning in the azimuth direction.SOLUTION: A radar reception signal processing apparatus 2 includes: an electronic scanning information acquisition section 21 for acquiring radar reception signals and information in an observation azimuth direction for each elevation direction within each sector in the azimuth direction; and a radar reception signal interpolation section 22 for calculating radar reception signals for each of the elevation direction in the indication azimuth directions in each sector in the azimuth direction, on the basis of the radar reception signals and the observation azimuth direction within each sector in the azimuth direction and in each elevation direction within each of adjacent or nearby sectors.SELECTED DRAWING: Figure 3 【課題】本開示は、方位角方向の機械走査を行ないながら仰角方向の電子走査を行なうレーダにおいて、１回のＲＨＩ観測での観測方位角方向の変化に伴うレーダ受信信号データの表示上の位置ずれを防止することを目的とする。【解決手段】本開示は、方位角方向の各セクタ内での仰角方向毎のレーダ受信信号及び観測方位角方向の情報を取得する電子走査情報取得部２１と、方位角方向の各セクタ内及び各セクタの隣りの又は近傍のセクタ内での仰角方向毎のレーダ受信信号及び観測方位角方向に基づいて、方位角方向の各セクタ内での表示方位角方向における、仰角方向毎のレーダ受信信号を補間により算出するレーダ受信信号補間部２２と、を備えることを特徴とするレーダ受信信号処理装置２である。【選択図】図３
