The ambiguity function characteristics of FSK/PSK (frequency shift keying/phase shift keying) signals based on the Costas frequency hopping technique are presented and compared to those of FSK/PSK signals based on quantized linear frequency modulation. The Costas-based FSK/PSK signal is found to maintain a high Doppler tolerance while yielding instantaneous spreading of the component frequencies along with enhanced range resolution. The question of whether PSK encoding should be performed from frequency to frequency or over each frequency separately is addressed through specific examples. The overall results give the radar designer a much freer hand in the selection of the transmission bandwidth, range resolution, and PRF (pulse repetition frequency) duty cycle.<>
