In a local monitoring device to Doppler radar, the oscillator, the antenna, the detector and the connecting lines thereof are formed in a microstrip structure and arranged on the same support material. This provides a flat construction and occupies little space, easy to manufacture and a device ...

What is so special about Doppler Radar Weather? In Doppler radar weather pictures, we are able to see air information that is not available in other media. What is the process? Do you have concerns about air pollution in your area?? Perhaps modelling air pollution will provide the answers ...
- 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:
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...
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 ...
Designing the radar For radar applications high frequency is needed for smaller resolution. High frequency also allows using smaller antennas because wavelength is smaller. Unfortunately going to too high frequencies is going to get too expensive, component selection starts to be very limited and the ...
