A Dielectric Waveguide based Signal Distribution Network for Time Multiplexed Fixed Target Radar Measurements

This contribution handles the design of a broadband, dielectric waveguide based, signal distribution network at mmWave frequencies, which is applicable for non-conventional radar metrology. It provides a broadband multi-port, equal transmission behavior as well as time gating capabilities. Theoretical derivations concerning equal power distribution and time domain separations are presented with respect to transmission line losses and available bandwidth. Next to the fundamental design considerations, simulation and measurement results, proving the network's applicability, are presented and discussed in detail.
