Abstract :
In this study, the detection of metal objects concealed under clothes is investigated through millimeter-wave inverse synthetic aperture radar (ISAR) imaging. A metallic gun is selected as the target and W-band ISAR measurements for a two-dimensional scanning geometry are carried out in our anechoic chamber measurement facility. The ISAR images of concealed object are reconstructed using the near-field back-projection algorithm. The obtained images indicate the efficient detection and identification of the gun covered with different textile types.
