However, as Westra and many other sources point out, UHF and VHF-band radars have historically had some major drawbacks. ¡§Poor resolution in angle and range, however, has historically prevented these radars from providing accurate targeting and fire control,¡¨ Westra wrote.

Northrop Grumman and Lockheed Martin appear to have overcome the traditional limitations of UHF-band radars in the APY-9 by applying a combination of advanced electronic scanning capability together with enormous digital computing power in the form of space/time adaptive processing.

A. RSTER: The RSTER is a UHF (406 to 450 MHz) air surveillance and tracking radar. It uses fourteen separate channels to output combined peak and average powers of 140 kilowatts (kW) and 8.4 kW at the transmitter flange, respectively.

B. MSSTIC Radar: The MSSTIC is also a UHF (406 to 450 MHz) air surveillance and tracking radar. The MSSTIC radar will use twenty seven separate channels to output combined peak and average powers of 270 kW and 16.2 kW at the transmitter flange, respectively.

C. UESA Antenna: The UESA antenna consist of an array of 54 elements installed at the outer edge of a disc shaped antenna 24 feet in diameter and 2.5 feet high. The transmitted output and received signals of the elements are combined to form the antenna's beam. The UESA will have different horizontal gain patterns when fed by the RSTER or MSSTTC radar due to the different amount of channels use by each radar."

Can China¡¦s New Destroyer Find U.S. Stealth Fighters?

"according to industry sources, there may be a way to reduce the size of the large radar resolution cells generated by lower-frequency radars¡Xto include UHF and VHF band systems.
The key is networking, industry sources said. If multiple low-frequency radars are connected via high-speed data-networks, it is possible that the resolution cell could be refined to the point where a missile could be guided onto that target.
Currently, it isn¡¦t known if any potential U.S. adversary possesses a similar capability, but it¡¦s a remote possibility.
However, it is not inconceivable that Russia or China could be working to develop such networked systems. In fact, according to industry sources, both nations are likely to be working diligently to develop such capabilities."
