Abstract
In this paper, the performance of the narrowband channelized radiometer that have a short detection time and high time-resolution was verified based on the theoretical formula. According to the simulation result, the channelized radiometer showed 2.5 dB superior detection performance compared to the broadband radiometer, but is more sensitive to the effects of noise than the broadband radiometer. Also the signal-to-noise of a channelized radiometer was changed dramatically according to the hop rate and jitter effect, which is linearly decreased as the change of two parameters.
