Abstract
Coherent Pulse-Doppler radar systems, whether used for synthetic aperture imaging or surveillance purposes, generally transmit a coherent pulse train made up of identical pulses. While these pulses may contain complex modulation---for example, linear FM chirps or frequency and phase coding---the fact remains that these pulses are usually identical. In this paper, we consider the potential advantages of pulse-trains made up of pulses that are distinctly different from pulse-to-pulse. In particular, we investigate a signal processing algorithm that provides increased resolution and discrimination through delay-Doppler sidelobe suppression in the region surrounding the mainlobe of the delay-Doppler response.
