Howeve r\, they cannot be trusted. All too often system engineers come a cropper due to believing the results of simulations without making sure that the r esults are correct and relevant. Significant errors can occur for many rea sons: bugs\, bugs\, bugs\, incorrect parameters\, incorrect physical model s\, incorrect application of perfectly fine code\, incorrect interpretatio n of accurate results\, etc. I was deeply shaped by a system\nengineering culture that valued simple back-of-the-envelope calculations to provide in sight into what was going on.

Fred was awarded th e Tom Phillips prize for technical excellence\, in recognition of his abil ity to make complex radar systems work in the real world.\n\nHe developed\ , analyzed and tested the real time algorithms for essentially all the lar ge long range phased array radars built by the USA in the last four decade s\, including: Cobra Dane\, PAVE PAWS\, Cobra Judy\, BMEWS\, THAAD\, ROTHR \, UEWR\, and SBX\, as well as several shipboard firecontrol systems and a ir traffic control systems. These real time algorithms include: extended K alman filters\, radar waveform scheduling\, Bayesian discrimination\, data association\, discrimination of satellites from missiles\, calibration of tropospheric and ionospheric refraction\, and target object mapping.
