Link budget calculations for nonlinear scattering [PDF]

2012 6th European Conference on Antennas and Propagation (EUCAP), 2012
Interest in harmonic and multitone radar has motivated new design efforts based on the standard approach found in the radar literature, i.e., the classical radar equation. In this paper we show that such approaches can be problematic in the presence of an active or nonlinear target, and indicate how a proper link budget should be constructed based on ...
