ABSTRACT

The Inverse Synthetic Aperture Radar (ISAR) generates an electromagnetic image of a moving target in accordance with the radar. This paper is about the technique of ISAR imaging of a moving target with respect to the radar. The Doppler frequency shift produces a backscattered data that is received by the radar. The target in general consists of many scattering points, which are very much necessary to analyze the performance of the targets reflectivity function i.e., target image and is obtained from the collected complex signal with the use of chip pulse technique in Matlab simulation. Range compression is employed to every single digitized pulse by pulse compression technique, which consists of matched filtering for every returned pulse with replication of original pulse. Subsequently, an Inverse Fourier Transform (IFT) operation is accomplished with the pulse index, in order range dimensions and also the noise at the receiver is suppressed.
