Abstract

Ambiguity function describes the measurement accuracy, resolution capability and ambiguity degree of signal delay and Doppler frequency shift, which can be used to analyze the resolution of adjacent targets and anti-interference performance of the system. In this paper, the binary digital modulation communication systems are considered, ambiguity function of the Direct Sequence - Binary Phase Shift Keying (DS-BPSK) is derived, and the performance of the signal interference is measured by the size of cutting area for ambiguity function. For 31 and 255 bits m-sequence spread-spectrum codes, the ambiguity functions are simulated. We conclude that the narrower the cutting area of ambiguity function the sharper the main lobe, the larger the resolution signal, and the stronger the anti-interference ability.
