“…With a conventional phased array, the instantaneous signal bandwidth in percent is approximately equal to the broadside beamwidth in degrees. Any larger bandwidth input signal will be spread over a larger beamwidth in space [ 5 ] . This limits the signal bandwidth for a 1.5 degree beamwidth antenna to about 85 MHz at C-Band and 45 MHz at S-Band.…”

The Aegis weapon system, now deployed in the USS Ticonderoga cruiser class and soon to be deployed in the Arleigh Burke destroyer class, is generally accepted to be, by far, the most capable ship AAW weapon system in the world. The concept for this system was developed in the mid‐1960s as replacement for the failed Typhon weapon sysem. During the concept design and early development phases there arose a number of key technical and programmatic issues. In retrospect, a different decision on many of these issues could have resulted in a much less capable system and, in some cases, to another system development failure. This paper first provides a brief description of the Typhon system concept and why it failed in execution. This is followed by the identification of key early technical and programmatic issues. Each issue is discussed, the options defined, and the final resolution described. With the benefit of hindsight, the impact on the system development from a different decision is suggested. Finally, an attempt is made to reach some general conclusions that could be of value to other similar development efforts.

“…A dynamic algorithm is one in which the forces acting upon the target are modeled and in which the estimated trajectory is constrained to obey the equations of motion determined by these forces. These equations will be of the general form x(ti+ 1) = Ax(ti) + Bu(ti) (1) where u(ti) is a control vector which is determined by the constraining forces. If some parameters governing these forces are unknown, these parameters must be estimated in order to describe and predict the motion ot the target.…”

“…The use of agile-beam electronically scanned array radars for space surveillance has permitted the realization of radar systems that can perform both search and track functions essentially simultaneously for large numbers of targets within the radar's zone of coverage [1 ] - [3] . The ability to position and shape the radar beam in microseconds under computer control permits the radar to interlace search and tracking functions so as to maintain track on many targets while continuing to search for new ones.…”

The factors which affect the target-handling capacity of an agile-beam electronically scanned multitarget-tracking radar are reviewed and analyzed. Consideration is given to the choice of strategy for dwell allocation among targets, the choice of trajectory extrapolation algorithms for target tracking, and the determination of saturation target acquisition rates. Emphasis is placed upon radar systems with control computers having limited speed and memory, .and recommendations are made for allocation strategy and targettracking algorithms, based on uniform sampling, to be used in maximizing the target-handling capacity in this situation.Manuscript received February 21, 1971.
