.3 Mm Band Radiometer Signal Acquisition And Simulation

This paper analyzes and simulates targets signals collected by a 3mm waveband radiometer, accordingly we can prepare for recognizing the targets.At first, the theoretic radiometer output waves are simulated, based on these signal waves, some rules between the signal waves characters and the targets information can been concluded.Secondly, we introduce the method of preprocessing radiometer output signals based on wavelet de-noise theory.Finally, we distill the eigenvalues from the preprocessed radiometer output signal waves, thus quantificationally analyze the rules between targets information and corresponding output waves characters to validate the rules concluded with theoretic waves . At the same time, we apply the reduced scale test to gather radiometer output signals.
