Abstract : Low frequency scanning radars operating near 2.8 GHz (S-band) and 5.3 GHz (C-band) are traditionally used to study severe weather and map rainfall because thesesystems experience low attenuation. Simulated and radar measurements presented in thisresearch demonstrate the utility of Ka-band and W-band radars for scanning in a tropicalenvironment.This work presents models that predict extinction rates due to atmospheric gases for35 GHz and 95 GHz radars as a function of elevation angle. The minimum detectableradar reflectivity (dBZemin) is computed for both wavelengths using radiosonde andmicrowave radiometer measurements. In general, sensitivity decreases with elevationangle mostly because water vapor and their corresponding highest extinction ratespropagate through the lower portion of the atmosphere.........-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
