FREQUENCY HOPPING INVERSE SYNTHETIC APERTURE RADAR IMAGING SIMULATION AIDED WITH REAL RADAR DATA

Innovative frequency hopping inverse synthetic aperture radar (FH-ISAR) imaging simulator was presented in this paper aided with the real collected inverse synthetic aperture radar (ISAR) data with conventional constant carrier frequency. These real data obtained by conventional ISAR was used as the input dataset to start the FH-ISAR Imaging simulation, and a series of virtual FH-ISAR dataset, which was simulated, or reproduced based on the input real dataset, were obtained given the parameters such as pulse numbers, frequency hopping bandwidth, frequency hopping code, etc. This simulator can also complete the imaging processing and series of clear images of non-cooperative targets which has the inherent precise complexities of real maneuvering target's movement, can be obtained. It provides a necessary and cool toolkit for FH-ISAR investigations.
