Tracking Performance of the Automatic Radar Equipment Mark 25 Mod 2 (Experimental Model) with the Gun Director Mark37 and Computer Mark 1
Abstract
To provide an estimate of the performance to be expected from the automatic tracking Radar Mk 25 Mod 2, preliminary tests on an experimental model of this radar have been conducted at Bell Telephone Laboratories by the Naval Research Laboratory with the cooperation of BTL engineers. The tests were carried out using aircraft flying at 170 and 230 knots on straight-line and evasive courses. The subject radar was mounted on an amplidyne-drive Gun Director Mk 37, and gun orders were generated by Computer Mk 1 Mod 13. The radial dispersion "s" of the tracking errors was between 0.4 mil and 0.8 mil for portions of the runs where the angular velocity of the target with respect to the director was less than 25 mils per second and between 1.1 mils and 3.2 mils for portions of the runs where angular velocities exceeded 25 mils per second.
