An improved maintainability concept for advanced radar systems
Abstract
An improved maintainability concept is presented for a very dense, complex digital signal/data processor in an airborne radar. The Line Replaceable Module (LRM) design concept, presented herein, results in a lower life cycle cost than is obtainable with conventional Line Replaceable Units (LRU's). This is achieved through fault isolation to the LRM by Built-In-Test (BIT) in the aircraft and replacement of the defective LRM at this level. Tradeoffs of weight, volume, and reliability are discussed to demonstrate the factors which led to the final design. A number of novel features which complement the overall design are discussed.
