MEMO : A Model for Evaluating Missile Observation Information.

A mathematical model, with JOSS and Fortran implementations, to simulate and analyze the information gathered by an observation system viewing successive launches from a missile complex, to compute certain statistics of the observation matrix, and to form an approximate solution to the empty-silo problem. The basic underlying assumptions are essentially the same for both JOSS and Fortran but because of JOSS's limited size the focus is primarily on Fortran. The discussion includes functional descriptions of the major subroutines, necessary and sufficient inputs, possible outputs, and suggestions to determine probable causes of errors. The information that MEMO provides can be used with other programs--a clustering routine and a solution program--to calculate a complete solution, although a very good approximation to the solution can sometimes be obtained by exercising MEMO alone. 64 pp. Ref.
