Effect of Sensor Errors on Automatic Gunfire Control

A formal approach is introduced toward mathematically relating errors in processed sensor data to their impact on error in gunfire of ground based, antiaircraft defense systems. An initial budget for sensor errors is formulated in terms of the accuracy requirements imposed upon the gunfire. The analysis is applicable to gun sites that are remotely located from the sensor as well as to colocated gun sites. Here, the radial components of sensor errors (along the sensor track line) are found to affect the target-miss distance of a remote gun by at least an order of magnitude more than their effect on the miss distance of a colocated gun. However, the effects of the traverse components of sensor errors (across the sensor track line) are found comparable in magnitude between remote and colocated guns.
