WebSep 16, 2024 · An object is often illuminated by a spatially incoherent light source and then imaged. The field reflected or transmitted by the object is then partially coherent. We have shown in Chapter 5 that the degree of mutual coherence in the object increases when the distance between the source and the object is increased. WebNov 16, 2024 · In [ 20 – 23 ], methods for multistatic ISAR imaging of moving targets have been presented. The study [ 20] describes the ISAR processing and fusion by coherent/incoherent summation in different overlapping situations of the radar network. The authors in [ 21, 22] develop the 3D reconstruction method based on a multistatic InISAR …
