A Multi-Channel Radar Receiver.
Abstract
A radar receiver design is presented that yields logarithmic and coherent signals of two orthogonal polarizations derived from each of two S-band transmitted frequencies. The radar is to be used for measuring Doppler velocity and polarization parameters of meteorological backscatter. The receiver design goals include phase and amplitude balance of 5 degrees and 0.5 dB between signals of opposite polarization. The logarithmic amplifiers are specified to have linearity of + or - 0.5 dB over a dynamic range of 90 dB. High-power ferrite switching devices are to be used to alternate the polarization of transmitted signals between orthogonal states on a pulse-to-pulse basis and to permit reception of co-polarized and cross-polarized signal components. Keywords include: Doppler weather radar; Dual frequency radar; Dual polarization radar; Multi-channel radar receiver, and Polarization diversity radar.
