I am doing the project with my friend. So, in this project every vehicle has a transmitter & receiver. Considering a particular vehicle we need to locate how many number of vehicles are there in its surrounding ( In the transmitter range ) along with the angle ( direction ) with respect to the car from which we are looking..
My friend was speaking about using radar.. he wants it to be installed in the system so that we could get this task done..
What I want to know : 1. Is this a possible solution? If not what else we can do to get this job done. 2. How much approx is going to cost for a small range Radar? 3. Suppose, there are 2 different vehicles separated by a distance of 10-20 cm in a traffic Jam.. can the radar show them clearly on the display / it will over lap the points on the display..
