This letter proposes a genetic algorithm-based beamforming design for integrated communication sensing and navigation (ICSN) in low-altitude scenarios. In the developed ICSN system model, communication performance is measured by the sum rate, sensing capability is evaluated through the Cramér–Rao bound (CRB) of angle estimation, and navigation accuracy is quantified by the positioning error bound (PEB). To efficiently solve the multi-objective optimization problem, a genetic algorithm is employed to obtain the Pareto-optimal solution set. Numerical results validate the proposed scheme in multi-target low-altitude scenarios and illustrate beam patterns under various performance trade-offs.
Aiming at the 6G air-ground integrated low-altitude sensing scenario, this paper constructs a networking model of multiple base stations and multiple UAVs. The sensing performance of 3.5 GHz (Sub-6 GHz band) and 26 GHz (millimeter-waveband) is compared. The algorithm principles and calculation processes of core links s...
