| Abstract: | A dual-band direct detect microwave radiometer is presented. The operating frequencies are 18.7 GHz and 36.5 GHz,and both frequencies are dual-polarization mode. The performance of the dual-band direct detect microwave radiometer had been tested and been compared with the dual-superheterodyne microwave radiometer. The result shows that with the similar performance,the direct detect microwave radiometer has the advantages of smaller size,lower power consumption and lighter weight,and it more suitable for sat... |
