AbstractA definite need existed for a high frequency, wideband, modular telemeter. This challenge was met with the development of two state-of-the-art projectile telemeters proven in support of the SADARM program. With the employment of existing gun proven designs, components, and software, two unique modular telemeters were designed. The modular design greatly facilitated testing and repair of these telemeters. Rail gun qualifying tests prepared these telemeters for use in high G environments. These gun rugged telemeters can withstand setback accelerations in excess of 12K G’s. Salient features of these telemeters include the use of numerous non-standard high frequency VCO’s, and a state-of-the-art transmitter with large deviation and data transmission capabilities. Emphasis is also given to design and application of a dual-van signal acquisition scheme. Deep nulls in the transmission antenna pattern were minimized with the employment of two receiving vans and an RF RERAD link between the vans which thereby enhanced transmission reliability. The scope of this paper includes an RF link analysis of the telemetry field test configuration. The facets elaborated upon include modular design, support software, and an in-depth electrical subsystem analysis. The major advantages of these telemeters is the employment of high frequency VCO’s with multi-channel capability for numerous simultaneous high frequency measurements.
