摘要

In this work, Wuhan University has proposed a vehicle mounted HF smart antenna system, which is used for anti-interference communication. Compared with existing work, the novelty of this work is as follows: 1. Propose a IF-based DBF hardware architecture, which has better stability and is easier to achieve channel expansion; 2. Verify the performance and limitation of existing superdirective beamforming method via field tests. 3. Propose and verify an effective anti-interference method by nulling technology. The experimental results prove that the system has good anti-interference performance.
