This site fucking rocks.
radartutorial.eu ain't that bad, either.

Umm... not yet, but I'll help you hunt, as this is relevant to my interests.

I've been reading up on radar a bunch recently, and while it's not EXACTLY the same, there are a lot of the same principles. For instance, the gain/directionality of an antenna is proportional to the ratio of aperture area to wavelength squared. Your emitter will likewise follow a similar law, and thus it will be desirable to use high frequencies (if possible) and a large emitter in order to form a coherent, flat wavefront.

How hardcore do you want this thing to be? Do you just want a ghetto-rigged sonic beam or something crazy like an electronically-steered phased array?

/k/ommando with a basic understanding of radar here.... pretty sure it was some sort of local interference.
