A personal radar would be nice for camping trips in grizzly territory :) I think over the years there were a lot of mini radars developed for the automotive applications - automatic braking and related. I think one new model car has this feature, but most of these efforts never got beyond the prototype stage. This kind of radar is typically a millimeter wave, frequency modulated, continuous wave radar, such as can be found at:
http://www.ducommun.com/ww_subsystems.html Don't know what they cost, but they look military-ish, and expensive. I think it wouldn't be too difficult to modify a Doppler radar, such as a cheap baseball speed gun, with a sawtooth frequency modulation to measure range. However, if I were going to do radar, I would rather use a laser rangefinder, like the Bushnell sports rangefinders. The standard ones are cheap, but they don't have a computer interface. You could either hack the innards or buy a more expensive version that has an RS232 interface. These have plenty of range. Here is a link for some other sensors for robotics, including scanning laser rangefinders and 3D flash laser cameras. Very expensive. http://www.acroname.com/robotics/parts/c_Sensors.html --~--~---------~--~----~------------~-------~--~----~ You are currently subscribed to the "R/C Tank Combat" group.
