Abstract
A method for measuring the frequency of continuous wave and wide pulse RF signals using multi-purpose, commercial-off-the-shelf test devices, such as an RF signal down converter, a digitizer and a signal processor. The method is based on digitizing the RF signals and dividing the digitized data into blocks of discrete data points. An initial estimated frequency is calculated for the first block of data and used to generate a synthetic signal. The synthetic signal and individual block of data under analysis are summed and tested by a discrimination function through an iteration process to arrive at an estimated frequency for each block of data points. The results are averaged to arrive at the final calculated frequency for the RF signal. The method is suitable for real-time calculations of the RF signal frequency.
