39087 仿真结果表明，本文提出的新算法在信噪比为-13 dB，采样点数为28时，检测概率达到96.21%，明显优于传统能量检测算法和传统拟合优度算法。 Results show that the new method proposed in this paper has a detection probability of 96.21% when the SNR is-13 dB and the number of sampling points is 28, which is significantly better than the traditional energy detection algorithm and the traditional goodness-of-fit algorithm.
39088 完好性信息的实时检测对于保证陆基增强系统(GBAS)基准站无故障运行至关重要，其中多参考一致性检测(MRCC)的B值是GBAS地面完好性检测的重要参数之一。 Real-time detection of integrity information is critical to ensure trouble-free operation of the Ground Based Augmentation System(GBAS) reference station.
39089 但传统的MRCC只能检测出故障基准站进而排除其所播发的改正信息，无法分析出基站信号的异常类型和程度。 Among them, the multiple reference consistency check(MRCC) B-value is one of the important parameters of GBAS ground integrity detection, but MRCC can not analyze the type and extent of signal anomaly.

The space-time two-dimensional vector correction and beam weight vectors of multi frequency points are used to obtain the difference beam weight vectors.
39095 最后进行和差波束形成，对每个样本和差比幅单脉冲测角。 Finally, the sum difference beam forming is carried out, and the angle is measured for each sample and the difference amplitude single pulse.
