Abstract :
A high resolution radar is currently under development at the Australian Centre for Field Robotics (ACFR) that will be mounted on a 4x4 vehicle and provide high fidelity measurements in range, height, angle and radial-velocity of targets and terrain within the local environment. The focus of this paper will be the dual-reflector monopulse antenna itself. The design of this antenna, including a theoretical analysis, full-wave electromagnetic (EM) simulations, Matlab simulations and experimental results indicate that dominant scatterers should be discernable over a limited height interval across the full slant range of the radar, albeit with degrading signal-noise-ratio.
