.3 Mm Band Radiometer Signal Analysis And Target Identification

This paper analyzes and simulates targets signals collected by 3mm waveband radiometer, accordingly we can prepare for recognizing the targets.This paper made the analysis and the simulation to the similarities and differences between full power radiometer and Dick radiometer. The theoretic radiometer output waves are simulated, based on these signal waves, some rules between the signal waves characters and the targets information can be concluded.The target signal of millimeter wave radiometer was decomposed to a series of projections in orthogonal subspaces by wavelet transform. The features of MMW radiometer were analyzed and characterized by Genetic Algorithm. At the same time, we apply the reduced scale test to gather radiometer output signals.
