In a Doppler radar device for local monitoring, the oscillator simultaneously constitutes the sensor. It contains a field effect transistor, provided in its source drain circuit and a circuit element for the collection of Doppler frequency signals, connected via a filter. This provides a particularly...

- Zoom and move map for close-up or wider area radar views - A long tap on radar map shows weather at that coordinate - Tap on weather to open detailed forecast - Tap on each forecast day to show hourly weather Other features: - Both imperial and metric units supported (F/mph or C...
These nine lattices are matched with the three-dimensional radar grid based on the neighboring method. Moreover, mark the value which is closest to the gauge rainfall record within the box of 3 km × 3 km area (totally nine values) as “Rr”. Meanwhile, the maximal value of radar QPE ...
24GHz Doppler RadarMW2401TR11 is a 24GHz human motion microwave sensor module product with high integration and a high intelligent algorithm, it equipped with the high-performance transceiver. The antenna not only has good directivity, but can also adjust the coverage area through software settings...
The agency is building a 142-foot radar weather tower that area residents complain would be a blot on a beautiful rural mountain range--and a health hazard because of microwave radiation. Advertisement What’s more, opponents charge the government with barging into their Eden--violating laws by...
DOPPLER RADAR. Police officers may not enjoy the comparison—given the public's general impression of bats as evil, blood-thirsty creatures—but in using radar as a basis to check for speeding violations, the police are applying a principle similar to that used by bats. Doppler radar, which ...
