Two antennas are used: one antenna measures what is transmitted by the radio transmitter and the other antenna is used to record the echoes from the radar targets. A passive radar is a special ...

The Local Radar base reflectivity product is a display of echo intensity (reflectivity) measured in dBZ (decibels). "Reflectivity" is the amount of transmitted power returned to the radar receiver ...

The weather is a realm of wonder, often leaving us in awe of its unpredictable beauty and power. Ground-based radar has become a tool of choice for meteorologists, enabling them to peer into the ...

RADAR observations on rain clouds are being made at Cambridge, using a vertically directed beam with a half-width of 3° to half-power, a peak power of 40 kW. with a 1 µsec. pulse on a wave ...

Conceptually, radar is pretty simple: send out a radio wave and time how long it takes to get back via an echo. However, in practice, there are a number of trade-offs to consider. For example ...

Introduction to both pulsed and C. W. radar systems. Detection of radar echoes in noise. The radar equation and its use in estimating performance of a radar system. Estimation of range, direction and ...
