Obscure mil doc: Telemetry Systems Radio Frequency Handbook

Posted on Friday, April 5th, 2013 in digital radio data, documentation, RF by the machinegeek

If you’re interested in obscure RF topics here’s a document for you. The Telemetry Systems Radio Frequency Handbook is a 133 page manual in PDF released by the US Army and found on the White Sands Missile Range website. It was prepared to assist in the development of improved RF telemetry transmitting and receiving systems in use on Range Commanders Council (RCC) member ranges. “This document is not intended to be a tutorial or textbook on the theory of RF systems design. It is intended to be a living document used to convey ideas, suggestions, lessons learned, and other items of importance to the new telemetry systems engineer or technician working in the field of RF telemetry.”

    I work at a radar R&D company, these guys will love seeing this RF handbook whose link you provided. Many old timers worked at some of the sites listed on the handbook. thanks.

    Maybe someone can explain why the Inter-Range Instrumentation Group (IRIG) time codes (the prolific IRIG-B in-particular) are pulse amplitude modulated so close to the modulation frequency? IRIG-B is a real pain in the neck to demodulate in near real-time (why? this a time-keeping code after all). How did they get around this before the likes of micro-controllers and/or DSP? Coherent demods (PLL)? Zero crossing detectors. Bucket analog or switched cap filters? I’ve always wondered about this.Given the wide dynamic range in amplitude of the IRIG-B phy spec., what’s the best approach?

    See here for more on the IRIG time codes (Wikipedia links from this page to the specs):
