What is a range bin in radar?
In weather radar, it is common to have a series of continual range gates that separate out returns at different distances and then process them to extract Doppler shift to measure wind speed. In these cases, it is common to refer to each gate as a range bin.
What is range on a gate?
The gate range is the amount of gain reduction that the gate closes down to. Therefore, if the range is set at 0dB, there will be no change in the signal as it crosses the threshold. If the range is set to -60dB, the signal will be gated (reduced) by 60dB, etc.
What is signal processing in radar?
The signal processor is that part of the system which separates targets from clutter on the basis of Doppler content and amplitude characteristics. In modern radar sets the conversion of radar signals to digital form is typically accomplished after IF amplification and phase sensitive detection.
What is range Doppler processing?
If a transmitter platform is stationary, a range-Doppler map shows a response from stationary targets at zero Doppler. For targets that are moving relative to the transmitter platform, the range-Doppler map shows a response at nonzero Doppler values.
