- Abstract
To deal with the difficulties of getting network positioning signals existing in sensor network as well as the problem of the hunted signals being polluted by electromagnetic radiation, mechanism of hunting for sensor positioning signals based on correlator difference accumulative algorithm is proposed in this paper. First of all, proportionality coefficient between the extreme value and second-extreme value of the interfering energy of the signals is selected as the mediation threshold to calculate the optimum value of the mediation threshold to capture the signals. After that, differential mechanism is designed to evade efficiently frequency shift resulted from Doppler factors of positioning signals; moreover, based on the frequency of Doppler high frequency positioning signals and the probability under low signal to noise ratio environment, theoretical analysis is conducted on the algorithm put forward in this essay in anti-noise performance and early warning performance. The simulation results have shown that compared with the current relevant sensor signal capturing techniques and under the same data receiving strength, the hunting algorithm raised in this paper has much higher early warning performance and anti-noise performance.
