Abstract
A weather radar display system is disclosed. The weather radar display system comprises a weather radar antenna, processing electronics, coupled to the weather radar antenna, enhancing weather radar returns based on a reflectivity model which differentiates lower level activity from higher level activity when the weather activity is detected from weather systems at long range and the reflectivity using short range thresholds would display only higher level activity. A weather radar display displays multiple colors representative of the different levels of weather activity based on the enhanced returns.
Claims20
A weather radar display system, comprising:
- a weather radar antenna;
- processing electronics, coupled to the weather radar antenna, enhancing weather radar returns based on a reflectivity model which differentiates lower level activity from higher level activity when the weather activity is detected from weather systems at long range and the reflectivity using short range thresholds would display only higher level activity;
- and
- a weather radar display displaying multiple colors representative of the different levels of weather activity based on the enhanced returns.
A weather radar display system, comprising:
- a weather radar antenna;
- processing electronics, coupled to the weather radar antenna, enhancing weather radar returns of long lines of storms detected at long range, the enhancement based on local averaging of weather radar returns, and produced in an iterative process;
- and
- a weather radar display displaying multiple colors representative of the different levels of weather activity based on the enhanced returns.
A method of processing weather radar display returns from long range weather radar, comprising:
- receiving the weather radar returns from long range;
- providing a model of the topical estimated fall-off of reflectivity level of conventional weather systems;
- applying the model to the received weather radar returns to recreate an approximate and undetectable fringe around the long range weather radar returns which may only detect high level weather activity;
- and
- applying conventional weather radar display thresholds.
A method of processing weather radar display returns from long range weather radar, comprising:
- receiving the weather radar returns;
- averaging a first subset of the weather radar returns;
- and
- adjusting the individual values of the first subset based on the averaging.
