Conventional versus Broadband Radar™
Conventional pulse radar uses a magnetron to generate a pulsed microwave signal that is transmitted from the rotating radar antenna. This burst of microwave energy is reflected off any target that it hits and returns to the radar, with the time it takes determining the range and bearing. This type of radar transmission is, in layman’s terms like shouting loudly in one direction and then listening to see if you hear an echo, turning and then repeating.
Broadband Radar™ uses a different type of technology that allows the radar to send out a continuous radar signal, with a changing tone or frequency, at a very much lower power and at the same time listen for the change in that signal. This is like continuously whispering and listening at the same time for the echo and is made possible by the radar using two antennas, one to transmit and another to receive.
The change in the tone of the transmitted radar signal determines the time taken for the signal to reach the target and return. This time determines the range and the bearing.
