Simulation of Coherent Radar Imaging Using Continuous Wave Noise Radar [PDF]
Journal of Atmospheric and Oceanic Technology, 2009 Abstract A computationally simple cross-correlation model for multiple backscattering from a continuous wave (CW) noise radar is developed and verified with theoretical analysis and brute-force time-domain simulations. Based on this cross-correlation model, a modification of an existing numerical method originally developed by Holdsworth
