The -117 sticks out like a very big, sore thumb at x-band and with OTH-B (think - Jindalee - a multistatic radar owned/operated by the fine folks in Oz) systems - which is why it was never a Naval attack system.

Can you source this please? Why would X band radar reflect back to the detector?

The -117 angles and all are designed for a specific band.

as an aside, OTH-B can even be used to track storm waves, it's all in the software.

No he can’t. It’s classified.
