Abstract
A single beam frequency modulated continuous wave radar for clear air scatter (CAS) detection and method of monitoring clear air scatterers are provided. CAS monitoring capabilities, including the ability to estimate wind velocity and direction, are obtained using data from a single defined width beam of energy that instead of being averaged is sampled at discrete time steps over a range of altitudes.
Claims11
A system for tracking clear air scatterer (CAS) wind speed and direction comprising:
- an emitter for emitting a single energetic beam of defined width across a series of altitudes;
- a receiver for receiving the signal from a return echo of the energetic beam;
- and
- at least one signal processor for processing the received signal configured to:
- identify the presence of at least one CAS,
- determine the boundaries of the at least one CAS using the defined beam width and the velocity of the at least one CAS,
- repeat the identification and analysis of target signal data over a series of discrete time steps and across a plurality of altitudes to create a data set of wind vector velocities for each of the least one identified CAS, and
- process the CAS wind vector velocities to determine at least a wind speed and direction.
