초록

What is provided is the use of an array of E-field sensors to detect the closest approach of incoming projectiles and to determine through time difference of arrival the bearing of the incoming projectile, thus to identify the bearing of the source of the projectile. dE/dT processing of the individual outputs of the E-field sensors indicates by the zero crossing the peak of the E-field disturbance and thus the instance of time of the closest approach of the projectiles to a sensor.

청구항

What is claimed is: 1. A method for detecting the direction of an incoming round, comprising the steps of: deploying an electric field sensor array having individual electric field sensors that sense the local static electric field about the sensor; using electric field sensors to sense a change in the local static electric field at the sensor caused by the incoming round; determining the time difference of arrival of the round by sensing maximum change in the static electric field adjacent each of said electric field sensors in the array; and, computin...
