Correlation receiver for doppler microwave landing system |
摘要 |
A processing apparatus for determining the frequency of a supplied signal is usable in a Doppler microwave landing system. The apparatus derives scalar signals representative of signal frequency and amplitude and computes the average value of the scalar signals over a number of time intervals prior to dividing the signals to produce an output signal representative of average supplied signal frequency.
