1. A method of reducing power to an electron emitting cathode in a weather radar system, comprising the steps of:
- a. sensing a weather condition within a distance of said weather radar system;
b. calculating a condition number based upon said weather condition;
c. comparing said condition number to a threshold; and
d. reducing the power to said electron emitting cathode when said condition number is greater than said threshold.

Abstract
A method of reducing power to an electron emitting cathode comprises the steps of sensing a weather condition; calculating a condition number based upon the weather condition; comparing the condition number to a threshold; and reducing the power to the electron emitting cathode when the condition number is greater than the threshold. The apparatus and method may be implemented upon a system having a high voltage power source, an RF tube, a control processor, and a signal processor.

13. A system for controlling the power to an electron emitting cathode in a weather radar system;
- comprising;
a. an antenna configured to sense weather conditions; b. comparators configured to compare said weather conditions to a plurality of threshold values and to output a threshold indicia; c. a summing block configured to sum said threshold indicia, said sum of said threshold indicia being a condition number; and d. a power level decision block configured to receive said condition number and to compare said condition number to a threshold to determine a power level for said electron emitting cathode. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A data structure for controlling the power to an electron emitting cathode, comprising:
-
a. a set of weather conditions; b. a set of weather condition thresholds; c. a comparator configured to compare said set of weather conditions to said set if weather condition thresholds, said comparator further configured to output a threshold indicia vector; d. a summing block configured to sum said threshold indicia vector, said sum being a condition number; and e. a power level decision block configured to receive said condition number and to compare said condition number to a threshold to determine a power level for said electron emitting cathode. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
