摘要： A method for computing and displaying a weather hazard threat level for a weather radar system of an aircraft includes receiving weather radar returns from a radar antenna of the weather radar system. The weather radar returns include at least one of horizontal scans and vertical scans. Radar reflectivity may be determined from the weather radar returns, and, for at least one of the horizontal scan data and the vertical scan data, areas of radar reflectivity and a temperature associated with the areas of radar reflectivity may be determined. A lightning flash rate may be estimated using the radar reflectivity, areas of radar reflectivity, and temperature associated with the areas of radar reflectivity. Weather radar information may then be displayed, wherein the weather radar information is adjusted on the display based on the lightning flash rate.

摘要： Method and apparatus for automatically adjusting the resolution of a CWFM radio altimeter includes a counter for counting a signal produced by the altimeter having a period relatable to the altitude desired to be measured. Another counter counts the number of pulses of a time reference signal occurring over a predetermined number of periods of the altitude related signal. The number of periods of the altitude related signal over which the time-reference-signal pulses are counted is automatically determined by a circuit responsive to the fullness of the time-reference-signal pulse counter to produce a signal after the counter has reached a predetermined count. The next occurring multiple of the altitude related signal is then determined, and the number of time-reference-signal pulses then counted is divided by the number of the multiple found.In a particular embodiment, the counters are binary counters, and the multiples determined are powers of 2, whereby the division is achieved by shifting the data in shift registers a number of places corresponding to the number of multiples of 2.sup.N found.
