View source for Range Information

A category of sensor information in the Command model.

Range Information indicates the distance to target.  This is obtained by measuring the time it takes for a sensor signal to travel to the target and return.

Sensor capability has evolved over time.  More sophisticated engineering
and processing of sensors has increased the type of information that can 
be obtained; older sensors are less capable.

Command distinguishes the sensor information types into:

 Space Search - ABM
 Air Search
 Surface Search
 Mine & Obstacle Search
 Periscope Search
 Submarine Search
 Land Search - Fixed Facility
 Land Search - Mobile Unit
 Altitude Information
 Range Information
 Heading Information
 Speed Information
