Abstract
The report describes the implementation of an intermediate frequency (IF) radar clutter generator. The generator provides signals for the monopulse tracking radar which forms part of the Electronic Warfare Engagement Simulation Facility at the Defence Research Establishment Ottawa. Land clutter signals with log-normal, Weibull and exponential spatial amplitude distributions are produced, as well as exponential sea clutter signals. Fluctuating clutter from wind blown scatterers is modelled using narrowband amplitude modulation. Clutter induced angle tracking errors are also represented. The report describes the major clutter mechanisms relevant to noncoherent radars in low grazing angle scenarios. The hardware and equations used in modelling are described, and the report presents envelope detected waveform plots and histograms. This work has applications in accurate modelling of radar performance in low-altitude engagements.
