Waveform control systems and methods for physical layer security in sensor and communication integration.

Abstract

The invention proposes a waveform control system and method for physical layer security in sensor-communication integration, configured to transmit, across multiple frame slots, a multi-carrier waveform characterized by at least one tunable waveform parameter and to receive single-station radar feedback signals corresponding to the multi-carrier waveform. A radar processor generates a delay-Doppler map, and a reflector detection and classification module detects reflectors and identifies an uncooperative reflector. An eavesdropping side geometry estimator estimates, for the uncooperative reflector, a round-trip delay and a round-trip Doppler and generates a one-way eavesdropping side channel model comprising path delay information, path Doppler information, and path gain information.A security optimization module determines, for candidate values ​​of a tunable waveform parameter, a sensor index, and a security index under a power allocation across variable domain resource elements, selects the tunable waveform parameter and power allocation, and coordinates with a frame scheduler and a feedback controller to update the operation across successive frames.
