APN-89 Doppler Radar

The APN-89 system uses doppler radar to provide ground speed and drift angle information to the ASb navigation system. The Doppler radar fed ground speed and drift information into the ASB navigation system. To calculate ground speed using Doppler radar, a radar signal is transmitted at a specific frequency that reflects off of the ground and returns to the plane. Since the plane's radar sensor is moving relative to the ground, the reflected signal will be shifted in frequency when it returns. This shift in frequency allows measurement of the relative velocity between the sensor and target. This, of course, is the same mechanism used in various speed detectors ("radar guns"), as well as in weather radar and many other applications.
