Normality Analysis for RFI Detection in Microwave Radiometry
Radio-frequency interference (RFI) present in microwave radiometry measurements leads to erroneous radiometric results. Sources of RFI include spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the “protected” band of operation, or out-of-band emissions not properly rejected by the pre-detection filters due to its finite rejection. The presence of RFI...
متن کاملRFI Mitigation in Microwave Radiometry Using Wavelets
The performance of microwave radiometers can be seriously degraded by the presence of radio-frequency interference (RFI). Spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the “protected” band of operation, or out-of-band emissions not properly rejected by the pre-detection filters due to the finite rejection modify the detected power and the estimat...
متن کاملUsing microwave radiometry for detection of breast cancer
It should be noted that thermal changes precede to the anatomical changes that can be detected by traditional methods such as ultrasonography, mammography and palpation. Thus microwave radiometry is a very promising method for the breast cancer detection at an earlier stage. Also it should be noted that as microwave radiometry measures natural electromagnetic radiation from the patient’s tissue...
متن کاملMicrowave Radiometry Imaging for Forest Fire Detection: a Simulation Study
This paper deals with passive microwave imaging for fire detection by means of a single-channel ground-based radiometer. The simulation of images sensed in the presence of fire spots under different environmental and operative conditions will be presented. We will refer to a low-cost ground-based radiometer operating at 12.65GHz. Scenarios where fires are un-visible and IR sensors are not usefu...
متن کاملDetection of Subclinical Synovial Inflammation by Microwave Radiometry
OBJECTIVE Microwave Radiometry is a non-invasive method which determines within seconds the in vivo temperature of internal tissues at a depth of 3-7 cm with an accuracy of ±0.2°C. In this proof-of-concept study, we tested the hypothesis that, in absence of relevant clinical signs, increased local temperature detected by microwave radiometry reflects subclinical synovial inflammation, using ult...
