A polyspectral LADAR optical breakscreen projectile sensor for reactive countermeasure queuing

An optical polyspectral sensor has been developed and tested which calculates the magnitude and directional velocity of an incoming projectile to queue a reactive countermeasure. This paper describes the sensor modeling, sensitivity analysis, and experimental results of a sensor consisting of four sheets of light. Sensor application could be extended to all projectiles that present a measurable laser radar cross section to the sensor.
