Background: Airport workers are continuously exposed to different levels of radiofrequency microwave (RF/MW) radiation emitted by radar equipments. Radars are extensively used in military and aviation industries. Over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile ...

These authors investigated the potential link between pilots’ exposure to non-ionizing radiation and the incidence of cancer. Mortality statistics were reviewed for 2,740 pilots using standardized mortality and incidence ratios (SMR) & (SIR). Rates were contrasted with a non-exposed referent population. The preferred relative risk model for radiation-induced nonchronic lymphoid leukemia (Beir V...

abstract obtaining reliable precipitation observations is important for hydrological simulations and weather forecasting. radar data can provide insight in the spatial variation of precipitation and can also detect large areas of rain and estimate rainfall rates. weather radar systems nearly always operate in s-, c- or x-band. since x-band systems require smaller antennas than those at c- or s-...

Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...
