TBMD Tactical Telemetry Transmitter

"Technical Abstract: Upgraded telemeter requirements for TBMD(Theater Ballistic Missile Defense) post-launch monitoring willinclude a new tactical mode for defensive operations during armedconflicts. Multiple Standard Missiles from multiple platformsmay be launched nearly simultaneously. System analyses haveindicated that under this scenario and current IRIG PCM/FMchannel allocation guidelines, unacceptable adjacent channelinterference will degrade critical telemetry communications.In aPhase I program, Nova Engineering, Inc. applied its technologystrengths in high spectral efficiency signals to theidentification of modulations, coding, and their implementationfor a solution offering up to 2.5x increase in the number ofchannels available (vs. PCM/FM).The proposed Phase II programwill realize a second generation architecture, suitable formissile shock / vibration environments, in a 15 cubic inchpackage. The all-digital waveform generation provides the threemodulations, plus future expandability to an infinite variety ofsource coding and modulation possibilities. Physical size andspurious signal goals are achievable through an advanced highefficiency power amplifier design (patent pending), eliminating aswitching power supply.The units will meet IRIG 106-01requirements in a mechanical package optimized for small size.The program will conclude with a demonstration and delivery oftwo transmitter units and specification documents.BENEFI
