Abstract:
1. An active chaff to be released by an aircraft to assist the aircraft in evading at least one of radar detection or a missile comprising: a radio transmitter configured to generate at least one waveform to assist an aircraft in evading at least one of radar detection or a missile; a signal spreading device configured to spread the at least one waveform; a microprocessor configured to control the radio transmitter and the signal spreading device; a power source configured to power the radio transmitter and the microprocessor; and a substantially high-drag aerodynamic envelope; wherein the active chaff has a longest dimension in a range of 4 to 25 millimeters and a weight in a range of 25 to 100 milligrams, and wherein the substantially high-drag aerodynamic envelope allows the active chaff to fall in air with high-drag under a force of gravity, prolonging a time the active chaff remains in the air, without the active chaff being self-propelled to fly.
