Multiple-access datalink communication networks (DCNs) are widely used in civil and military communication systems, such as global positioning system and joint tactical information distribution system. With the development of digital signal processing technologies, strong countermeasures, such as block jamming and aiming jamming bring significant challenges to the communication performance of multiple-access DCNs. Meanwhile, cancelling countermeasures whose direction and timing are unknown can be potentially enriched by antenna arrays, thanks to the strong spatial resolution of antenna arrays. This paper analyzes the cancelling performance of strong broadband countermeasures using antenna arrays in multiple-access DCNs. Signal and array models are established taking broadband countermeasures into consideration. Closeform solution expressions of discrete systems are derived, while the analytic expressions of the stability performance and convergence speed of broadband countermeasures cancellation are deduced. Extensive numerical results demonstrate the accuracy of the derivation. The elevational and horizontal dimension pattern of the antenna array are also presented through simulation.
