Abstract :
The equations of motion for a radar scan that provides a nearly constant number of pulses to all point targets are derived. In addition, the periods for this scan and for the more conventional one having constant angular velocities are presented. For these types of scanners it is found that the optimum cross-over point between adjacent beams is at the 2.1-db point of the antenna pattern.
