Abstract:
(EN) An SAR image generation unit (21) generates SAR images for a radar device (10). A registration unit (22) aligns each SAR image using speed information for a platform measured by a motion measurement unit (30). A signal calibration unit (23) compares the SAR images and corrects amplitude and phase imbalance in the SAR images. A moving target detection unit (24) calculates the phase differences between the SAR images corrected by the signal calibration unit (23) and detects a moving target by comparing these phase differences.
(FR) L'invention concerne une unité de génération d'image SAR (21) qui génère des images SAR pour un dispositif radar (10). Une unité d'enregistrement (22) aligne chaque image SAR à l'aide d'informations de vitesse pour une plate-forme mesurée par une unité de mesure de mouvement (30). Une unité d'étalonnage de signal (23) compare les images SAR et corrige un déséquilibre d'amplitude et de phase dans les images SAR. Une unité de détection de cible mobile (24) calcule les différences de phase entre les images SAR corrigées par l'unité d'étalonnage de signal (23) et détecte une cible mobile par comparaison de ces différences de phase.
(JA) SAR画像生成部(21)は、レーダ装置(10)の各SAR画像を生成する。レジストレーション部(22)は、運動計測部(30)で計測されたプラットフォームの速度情報を用いて、各SAR画像の位置合わせを行う。信号校正部(23)は、各SAR画像を比較し、各SAR画像の振幅及び位相のインバランスを補正する。移動目標検出部(24)は、信号校正部(23)で補正された各SAR画像間の位相差を算出し、これらの位相差を比較することで移動目標を検出する。
