be detected at detector 24 and decoded as muzzle flashes by the monopulse muzzle flash electronics network 130 the muzzle flash signal from the network 130 if the muzzle flash is the highest priority target detected will be coded with a distinguishing repetitive rate and pulse length by the pulse shaping digital display converter 134 from the converter 134 the coded pulses are fed to the invisible to visible converter 26 causing the light emitting diode in the corresponding sector of the light display to be illuminated for example led 62 would be illuminated to indicate a muzzle flash in that direction and distance the light from led 62 is superimposed on the gunner 39 s sight scene and appears at infinity by the effect of lens 28 thus the operator is capable of turning the sight to center the pipper 60 on the location of the muzzle flashes when the muzzle flashes are bore sighted an indication will be provided on all four lights 64 the central portions of the detector 51 are providing a proportional signal throughout the aiming process indicating the angular error and orientation for use in the gun control computer and gun aiming system at this stage the gunner may elect to commence firing based on the visual line of sight or can turn the system over to the gun mounted sight allowing the system to automatically update the aim based on continuing muzzle flashes and upon the angular error as evidenced by impact flashes in the case of a cooperative target that is a target which is either illuminated by a.
