ABSTRACT:
A helicopter combat device for detecting flying objects and for causing a ground-to-air mine to be fired at them, comprises a microphone which is sensitive to noise generated by a helicopter, an infrared sensor having a directional characteristic which is within the firing cone of the ground-to-air mine, and an electronic evaluation unit which receives and processes electrical signals generated by the microphone and the infrared sensor. The electronic evaluation unit separates the electrical signals received from the microphone into a first band corresponding to noise having a frequency in the range of 5-40 Hz (typical of a rotating rotor of a helicopter), and a second band corresponding to noise having a frequency in the range of 200-1000 Hz (typical of the machine noise of a helicopter). If the electronic evaluation unit detects the presence of electrical signals from the first and second bands and electric signals from the infrared sensor above predetermined threshold levels, it will cause the ground-to-air mine to fire.
