Computer generation of ambiguity surface for radar waveform synthesis

Recent advances in the field of surface acoustic devices are likely to encourage the implementation of complex forms of matched filter radars. As a consequence, the system designer and EMC Analyst will require convenient methods establishing the likely system performance obtained from the various forms of signal processing. One well established technique used to determine the theoretical performance of matched filter or correlation receivers is through the application of the ambiguity function. This function has wide application as it may be employed to evaluate the theoretical received signal response in both the time and Doppler domains. As this function handles both matched and unmatched signals it provides a convenient method of assessing both the design and eventual electromagnetic compatibility of the system. With these considerations in mind a general computer method of solving the ambiguity function has been developed and is described in this paper.
