  Abstract

This paper implements and verifies the notch filter based anti-jamming scheme, which has been conventionally proposed to enhance the survivability of the unmanned aerial vehicle (UAV). As a performance metrics, this paper employs signal to noise ratio (SNR), initial synchronization acquisition time, and anti-jamming performance against to the tone jamming signal. According to the hardware implementation and performance test results, in case of low jamming to signal ratio (JSR), the proposed scheme shows the lower SNR performance(approximately less than 1 dB or similar depending on bandwidth) because the proposed scheme suppresses the more effective signal than the conventional nulling-based anti-jamming scheme. However, in case of higher JSR (e.g. 20 dB), the proposed scheme outperforms the conventional scheme because jamming signals are much more suppressed than the effective signal(approximately 1∼4 dB better performance regardless of bandwidth). In conclusion, it is expected that the proposed notch based anti-jamming scheme will improve the survivability and reliability of a satellite data link if it is applied to a satellite-based datalink system.
