The present invention is a radar system that detects turbulence by breaking a range cell return down into spectral segments using an FFT processor. The standard deviation of the spectrum is determined and the system compares that standard deviation to a reference threshold of a non-turbulent return if the signal is above noise. If the threshold is exceeded, the range cell is marked for turbulence display. Once the turbulence display is completed it is overlayed on the weather display. To improve matching of the feature size to the variance calculation the invention performs both range and azimuth post detection integration subsequent to the FFT but before variance calculation.

Turbulence radar system

A system for real beam radar ground mapping using a monopulse antennae to determine off-boresight angle of target returns. Off-boresight angle is converted to azimuth bins. After processing, return energy for each contiguous azimuth bin of an illuminated area is dumped during a respective 'look' of the antenna.
