Modern airborne electronic computer implement pulse detection algorithms, that are fundamental for interpreting signals from ground station interrogations and laser-optical warning systems. These systems play a crucial role in aircraft’s situational awareness and threat mitigation, in particular in complex operational environments. These type of algorithms require efficient signal processing capabilities while maintaining high detection accuracy, in order to be capable of identifying fast and transient pulse signals while minimizing false detections. At the same time, these algorithms must maintain low latency and minimal hardware overhead, in order to ensure optimal real-time performance that are typical of modern avionics systems. To address this challenge, the use of High-Level Synthesis (HLS) tool within a model-based design framework provide a promising approach for implementing signal processing algorithms on FPGA platforms.
