The Response of a Panoramic Receiver to CW and Pulse Signals

An analysis of the response of a panoramic receiver to cw and pulse signals is presented. The receiver´s response is studied quantitatively as a function of the parameters: signal-pulse length and frequency, receiver bandwidth, sweep-rate, and type of IF amplifier. The effect of these parameters on the relative output amplitude, output pulse width, and apparent bandwidth is emphasized. Two specific cases are considered. An electronic differential analyzer is used to study the response of a receiver with a single-tuned IF amplifier to pulses having rectangular envelopes. Theoretically the response of a receiver with a Gaussian shaped IF pass-band to pulses having Gaussian envelopes is derived. This answer is given in closed form. The agreement between these two cases justifies the application of the Gaussian case to most practical design problems.
