scope:

This specification establishes the requirements for the design, development, construction, performance, testing, installation, and system integration of a solid-state receiver and digital moving target indicator (SSR/DMTI) modification kit to replace vacuum tubes and associated circuitry in the receiver subsystem of vacuum-tube air route surveillance radars (VT ARSR) with solid-state devices and digital circuitry to improve reliability and maintainability, to improve system performance and to improve the operating efficiency of the receiver system.
