Tactical Air Surveillance Radar Netting (TASRAN) simulator/emulator

TASRAN is a computer simulation for evaluating netted tactical air surveillance systems. TASRAN can model user-defined networks of groundbased radars, and it can exercise this radar network against user-defined scenarios of hostile and friendly aircraft on specified flight paths. The data processing functions of radar detection, track initiation and correlation, and automatic target tracking are performed (not merely simulated) on the simulated measurements from the network of radars. Communication from site to site can be modeled in various levels of detail, from simple message routing to resource sharing and delays to detailed calculations of propagation and jamming degradation. Simulation outputs can be summarized in printed tables or in interactive displays at a Tektronix terminal. The computer program is installed on RADC's Honeywell 6180 computer system; an identical version is installed on GRC's DEC VAX-11/780, where all of the code was developed and tested.
