The potentially wide bandwidth and large storage capacity of optical recording and processing systems leads naturally to consideration of direct IF recording. A method of recording and processing IF pulse-Doppler signals is presented and it is shown how ambiguities are reduced, compared to video processing, in the manner expected from sampling theory. Processing of a linearly varying Doppler frequency is also discussed. Experimental results with simulated constant frequency and linearly varying frequency recordings are shown.
