I would imagine the lower end of P-Band would be effective against stealth. In fact I've heard AWACS use these freqs around 400mhz. From what I understand of stealth, the cut angles and spacing of the sawtooths under the outer skin are designed for mimimal reflection of microwave wavelengths. A longer wavelength like UHF would probably result in less absorption and more refraction, so I'd guess they'd need to use an array of receivers to find the refractions and then calculate the position of the aircraft since the longer wavelength probably wouldn't give a clean direct reflection like microwave does.
: "In a nutshell! When an object (bogies) passes through the transmitted signal, it causes receiver interference (anomalies)." <----Yes an ty wayne, this is what i was reffering too... or trying to reffer to rather. i wanted to ask the board about it before i explored the topic...as it is so completely foreign to me. I guess the 800mhz model of this technology is the one that comprimizes the US stealth fleet the most? Again i have know idea. It will be interesting to find out though. Ty for the input.
