Synthetic Aperture Radar
Synthetic Aperture Radar (SAR) is one of the important airborne imaging sensors for surveillance, reconnaissance and precision targeting. Being a day/night, all weather imaging system unlike its electro optical and thermal counterparts, SAR forms an indispensable system for the Defence applications. The imagery and the ground moving target information from the SAR can also be used to guide weapons. Key features of SAR include stripmap mode imaging, spotlight mode imaging, GMTI mode for detecting moving vehicles on ground.
