摘要:
An airborne wind shear detection radar includes a transmitter for transmitting successive radar beams into airspace in front of an aircraft and a receiver for receiving reflected signals. The radar analyzes the received reflected signals in the frequency domain to determine if a wind shear condition exists in the airspace in front of the aircraft.
摘要:
A radar system alternately transmits relatively short and long pulses. The video signals corresponding to the target returns from consecutive pulse transmissions are converted to digital format and then integrated except that radar return signals from targets within a first range resulting from long pulse transmissions are not used for integration.
摘要:
An aircraft air speed signal is differentiated to provide a signal related to rate of change of air speed. This signal is added to a signal related to aircraft barometric altitude change with the sum signal being compared against aircraft radio altitude to generate warning if the aircraft rate of descent is excessive for the conditions encountered.
