Abstract: A Pulse Signal Accumulation System for determining target proximity in supersonic and ultrasonic flying devices comprises the following components: digital processing block, high-frequency transceiver block, power supply block, antenna block, and communication block. The system is designed to accurately determine and provide alerts for the presence of targets within the influence zone of unmanned aerial vehicles (UAVs) operating at supersonic or ultrasonic speeds, enabling appropriate actions to be taken by the UAVs. Additionally, the system is equipped with self-checking and monitoring capabilities for the individual components within the overall system.
