Paper Abstract

In order to quantitatively analyze the transiting performance of 8 millimeter wave passed through non-pure atmosphere environment and study the attenuation laws of aerosol, sand storm, fog, haze and other various complex media to millimeter wave, a set of 8 millimeter wave detecting system to test the insertion loss has been designed and composed of a transmitter with standard adjustable attenuator, amplified superheterodyne receiver, computer control software and other components. The system works in the frequency of 33.7GHz and the effective testing range is bigger than 600m. The insertion loss is bigger than 20dB. The testing error of insertion loss is smaller than 0.2dB and the minimum interval of sampling time is 0.5s. The calculation principle of insertion loss and attenuation rate for various media to millimeter wave have been studied while a set of computer software has been designed to analyze the inserting experimental data. Some inserting experiments have been completed with various millimeter black-bodies to study the performance of the 8 millimeter wave detecting system. By the experimental results, the system has a lot of good performances, such as stronger signal, big testing range, good sensitiveness and stabilizer capacity.
