What type of radar is utilized for inverse synthetic aperture?

The utilization of inverse synthetic aperture radar (SAR) is specifically designed for generating high-resolution images of targets by exploiting the motion of the radar platform. Unlike conventional synthetic aperture radar, which processes data from the movement of the radar sensor to create images in the range direction, inverse synthetic aperture radar focuses on the velocity of the target in the elevation or cross-range direction. This allows for detailed imaging of moving targets, making it highly effective for applications such as tracking vehicles or aircraft.

Inverse synthetic aperture radar employs advanced signal processing techniques to achieve this, utilizing the Doppler effect generated from target movement to enhance resolution. This distinction in focusing on the target's motion is what sets inverse synthetic aperture radar apart from the other types of radar listed in the options, reinforcing its unique effectiveness in specific scenarios.
