Time on target (TOT) is the military co-ordination of artillery fire by many weapons so that all the munitions arrive at the target at roughly the same time. The military standard for coordinating a time-on-target strike is plus or minus three seconds from the prescribed time of impact.
The law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. [1] Fitts's law is used to model the act of pointing , either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor ...
Early in World War II, target range and bearing measurements were taken over a period of time and plotted manually on a chart. [14] The speed and course of the target could be computed using the distance the target traveled over an interval of time. During the latter part of World War II, the speed of the target could be measured using radar data.
During World War I, computing a target intercept course for a torpedo was a manual process where the fire control party was aided by various slide rules [13] (the U.S. examples were the Mark VIII Angle Solver (colloquially called the "banjo", for its shape), and the "Is/Was" circular sliderule (Nasmith Director), for predicting where a target ...
A missile (blue) intercepts a target (red) by maintaining constant bearing to it (green) Proportional navigation (also known as PN or Pro-Nav) is a guidance law (analogous to proportional control) used in some form or another by most homing air target missiles. [1]
Target Motion Analysis (TMA) is a process to determine the position of a target using passive sensor information. Sensors like passive RADAR and SONAR provide directional and occasionally frequency information. TMA is done by marking from which direction the sound comes at different times, and comparing the motion with that of the operator's ...

Simple trigonometry can calculate the angle that the target would appear when the aircraft was at the drop point. This is known as the range angle or drop angle , and was typically looked up from a set of pre-computed tables or using a simple mechanical calculator .
