In this video, we solve a numerical problem on radar echo return time using electromagnetic wave relations.
Problem:
A radar sends an electromagnetic signal of electric field E0 = 2.25 V/m and magnetic field B0 = 1.5 × 10−8 T which strikes a target on line of sight at a distance of 3 km in a medium. After that, a part of signal (echo) reflects back towards the radar with same velocity and by same path. If the signal was transmitted at time t = 0 from radar, then after how much time echo will reach to the radar?
