One of my first "elaborate" circuits, a simple photon pulse radar. It's somewhat realistic because the photons are emitted as a curved burst rather than a straight line like the other lasers, thus you get an interesting simulation of Radar-Cross-Section and it also works with things that are not perfectly flat. I did two planes to illustrate this, one a normal plane with a radar warning receiver and the upper one being a stealthy, low-RCS F117-like design with "radar"-absorbing material, glass. The radar works on time to find the range, since i roughly calculated that a normal photon has a speed of 1.33cm/s; so you can find out the range by the same manner as a real radar.

Right now it has only 3 range sensibilities, close medium and far. I downsized the design size at least 50%, it also now uses less photons for the same job as compared to the old, big version. Mk.2 will have better range sensibility (up to 6 possibilities), i'll work on that. You can see the "Magnetron" (Photon-pulser) made of walls at the middle wich is the core of the design. Photons that bounce back are capted by the antenna(s) and the signal lights up the AND gates that are successively traveled by the signal from the timer, so you get a match where Time and Echo meet.

I will make a small radar jammer in the non-stealth, it is basically a magnetron that activates when the RWR warns of radar waves; it sends fake radar waves to create false readings in the range gate. By, as it's known in Electronic Warfare, stealing the range gate; sends a radar signal with a different speed than the real echoes; and makes his range appear closer or farther than he actually is. WIP.

Please Rate and comment :D

Edit: Already an improved version, but no points because i just adapted the best Radar i could understand to my uber-antenna. Now has 7 or 8 ranges and, oh my the technology, a decimal number LED! Included the original designer's crests as further credit, cause it's damn good work. So now we have the best of both worlds.

I think i know roguegeneral, Negative or Positive silicons will totally absorb photons, but current Radar-Absorbent-Material isin't as good as that. Nope. Not even the B2 or Raptor. I found that glass has the desired effect since it traps it inside sometimes and sends it back slower thus messing up the range reading. I did my homework :P

PowderToy Cold Way eh... Hmmmm....
