On 18 March 2008, Boeing, with ImSAR and Insitu successfully flight-tested a ScanEagle with ImSAR's NanoSAR A radar mounted aboard. The ImSAR NanoSAR is the world's smallest Synthetic Aperture Radar, weighs 3.5 lb (1.6 kg) [7] and is 100 cubic inches (1.6 litres) in volume. It is designed to provide high quality real-time ground imaging through ...
Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. A larger RCS indicates that an object is more easily detected.
The APG-77 has an incredibly fast scan time across its 120 degree field of view and could detect aircraft from over 320 mi (515 km) away. The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range.

The AN/AWG-9 and AN/APG-71 radars are all-weather, multi-mode X band pulse-Doppler radar systems used in the F-14 Tomcat, and also tested on TA-3B. [1] It is a long-range air-to-air system capable of guiding several AIM-54 Phoenix or AIM-120 AMRAAM missiles simultaneously, using its track while scan mode.
The radar's AESA technology provides quick updates on multiple targets, and its solid-state antenna construction makes it more reliable and cost-effective than traditional radar systems. [2] The radar has a range of up to 150 km (80 nm) and can track multiple targets simultaneously. [ 3 ]
Last week, the Biden administration announced a $3 billion military assistance package, which includes ScanEagle drones, unmanned aerial vehicles used for reconnaissance.
The cross-section is the minimum apparent surface area observed in the direction of the radar that must be detectable.. Radar cross section changes with aspect angle. Cross section for anything except a perfect sphere depends upon the aspect angle, which how far the reflector is rotated with respect to the radar pulse.
