Description: This 6U VME form factor card was designed for a defense contractor who wanted to add AIS (Automatic Identification System) to their airborne search and rescue radar system. To deliver this product, we relied on our expertise in hardware, wireless, FPGA/DSP, and embedded software design. The system highlights include an AGC system to provide incredible RF sensitivity, and an FPGA-based software defined radio DSP engine.
To bring-up, debug, and characterize this product, we used The Mathworks MATLAB® to generate a large number of test waveforms that we then loaded into our vector signal generator. In addition to extensive laboratory testing, we also had the opportunity to test our AIS equipment in various cities including Montreal, New York, Philadelphia, Seoul, and Istanbul.
