Abstract :
The civilian signal B2a of the Compass was interfered by pulse pairs in the DME/TACAN band. This paper introduces the Compass B2a signal and DME/TACAN signal spectrum structure, then compares the advantages and disadvantages of notch filter and pulse blanking and leads to the mixed blanking technology to enhance the anti-interference of B2a signal [1], which is a combination of the two technologies.
