METHODS AND SYSTEMS FOR REDUCING ACQUISITION TIME IN AIRBORNE WEATHER RADAR
First Claim
1. An airborne weather radar method comprising:
- serially generating a first radar pulse having a first frequency range based on a first received control signal and a second radar pulse having a second frequency range based on a second received control signal that does not overlap with the first frequency range;
serially transmitting the first and second radar pulses;
receiving reflected echoes from the transmitted radar pulses in parallel receive channels; and
processing the received echoes in parallel into a usable form.

Abstract
An airborne weather radar system and method. The method includes serially generating and transmitting first and second radar pulses having non-overlapping frequency ranges, receiving reflected echoes from the transmitted radar pulses in parallel, and processing the received echoes into a usable form. In an alternative embodiment, the method also includes serially transmitting at least one additional radar pulse having an additional frequency range that does not overlap with the frequency ranges of previously transmitted radar pulses in the serial transmission. The system includes a radar processor configured to serially generate a first control signal for a first radar pulse having a first frequency range and a second control signal for a second radar pulse having a second frequency range that does not overlap with the first frequency range. The radar processor also includes a second component configured to process received echoes in parallel into a usable form.

20. An airborne weather radar method comprising:
-
serially generating a first radar pulse having a first frequency range and a second radar pulse having a second frequency range that does not overlap with the first frequency range; serially transmitting the first and second radar pulses; receiving reflected echoes from the transmitted radar pulses in parallel receive channels; and processing the received echoes into a usable form, wherein receiving reflected echoes comprises; receiving a combined analog echo signal; converting the combined analog echo signal to a combined digital echo signal; and filtering the combined digital signal into a first echo signal corresponding to echoes received from the first radar pulse and a second echo signal corresponding to echoes received from the second radar pulse.
