AbstractA microwave frequency detection receiver for receiving an incoming analog radar signal, converting the radar signal into digital form, and performing a table lookup algorithm for detecting frequency and amplitude of the incoming signal with respect to time. The table lookup algorithm is in the form of a three point best-fit sinusoidal approximation of frequency and amplitude for processing successive digital input signal samples processed in groups of three. Digital sampling of the input signal coupled with the novel table lookup algorithm results in detection of frequency and amplitude characteristics on an intrapulse basis.
