Collocations With Radar
The modulation index driving on the obtain sign is proportional to the time delay between the radar and the reflector. The frequency shift is instantly proportional to the distance travelled. That distance may be displayed on an instrument, and it may even be out there by way of the transponder. This sign processing is just like that utilized in speed detecting Doppler radar. Since the sign frequency is changing, by the time the sign returns to the plane the transmit frequency has changed.
The radar mile is the time it takes for a radar pulse to journey one nautical mile, reflect off a goal, and return to the radar antenna...Read More
