The system and method for accurately determining range-to-go for the command detonation of a projectile. Using dual laser and/or radio frequency detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, or lateral offset from the projectile to the target.

Accurate range-to-go for command detonation

The system and method for accurately determining range-to-go for a time-delayed command detonation of a projectile. Using dual laser and/or radio frequency detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, and/or lateral offset from the projectile to the target. A time to detonation clock is used to determine when a projectile transitions from an exterior to an interior of a structure such that the projectile can more accurately detonate within a fixed structure.

Establishing a time zero for time delay detonation

The system and method for accurately determining range-to-go for the command detonation of a projectile warhead. Using dual laser detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, or lateral offset from the projectile to the target. The method for controlling a projectile warhead uses a large area PIN detector and an ogive window. If the PIN detector is large enough to capture the second laser signal, the window is no longer an optical element, only a window thereby drastically reducing the cost of the system. In some cases the detector on the nose of the projectile comprises several PIN diodes placed around the projectile as a distributed aperture. Distributed apertures may also be created by placing the PIN diodes on the wing roots or body of the projectile.
