A High-G Flight Experiment of a Field-Programmable Gate Array (FPGA) Pulse Code Modulation (PCM) Encoder

摘要

Recent successful testing of a Hardened Subminiature Telemetry and Sensor System (HSTSS) Field Programmable Gate Array (FPGA) Pulse Code Modulation (PCM) data acquisition solution provided launch and flight data for a modified tank training round that was launched from a 120mm smoothbore cannon with acceleration forces in excess of 30,000 times the force of gravity (g). The electronics board was designed and manufactured at Naval Air Warfare Center (NAWC) to include four channels of signal conditioning, eight-bit analog-to-digital conversion, and power source regulation. The Advanced Munitions Concept Branch (AMCB) at the Army Research Laboratory (ARL) integrated the board within a North Atlantic Treaty Organization (NATO) compatible fuze volume fitted with ARL patented optical sensors, a Microelectromechanical systems (MEMS) accelerometer, an HSTSS LiMnO_2 primary battery, and a commercially available high-g transmitter/antenna package. Results include operational success of the FPGA/PCM encoder and valuable ballistic and aerodynamic measurements.
