The Defence Research Establishment Ottawa has developed a Digital Radar Receiver and Data Acquisition System as part of an experimental air-to-air surveillance radar that will be used to demonstrate an air-to-air surveillance capability for the Canadian Forces CP-140 Maritime Patrol Aircraft. The report presents an analysis of the radar return signal expected from a point target, and predicts the existence of transient Doppler artifacts associated with the leading and trailing edges of the radar pulses. A software simulation also produces transient Doppler artifacts, and experimental measurements of a simulated target signal confirm their existence. The potential impact of the artifacts on radar performance is discussed, as are techniques to mitigate their deleterious effects.
