Counter-bird aircraft system using a Doppler detection device to alert pilots of an imminent bird strike threat

A counter-bird aircraft system, comprising:

• a Doppler detection device including at least one emitter positioned on an aircraft, the emitter to emit a continuous beam of radio-frequency energy in a fixed pattern ahead of the aircraft, wherein during normal flight conditions no return signal of the emitted continuous beam is received by the system;
• at least one receiver to detect a return signal of the emitted continuous beam reflected from a threat to the aircraft;
• a microprocessor to process the reception of the return signal and transmit an alert to an alert system, the alert to notify the pilot of the threat;
• and
• wherein the alert is transmitted for as long as the return signal is detected by the at least one receiver, and wherein the system intentionally provides no speed information of the threat, no range information of the threat, and no information about a target type of the threat to the pilot.
