Digital Simulation of Monopulse Angle Tracking with Multipath Propagation

摘要

The report documents recent efforts in digital computer modeling of multipath propagation effects on a modern tracking radar. Specific questions on the role of the earth dielectric constant and surface roughness are considered. Several earth models are also considered, including a flat smooth surface, smooth 4/3 radius spherical surface, and a 4/3 radius spherical earth with rough surface. Two basic scattering models are considered, specular reflection which is coherent in nature and diffuse reflection which is noncoherent. This study uses a large digital phased array radar simulation which will be described in detail in a future report. The parts of significance to this effort are described for completeness. (Author)
