摘要
针对应答着陆系统(Transponder Landing System,TLS)利用虚拟阵列基于MUSIC算法的空间平滑测角技术在实际工程中存在测角误差的问题,分析了测角误差的成因和影响因素,结合实际采用了一种综合误差校正方法并进行了仿真分析。仿真结果表明,该方法能够有效地解决误差,并在低信噪比条件下显示出了良好的性能,具有较高的可靠性。
Against the error of the spatial smoothing angle measurement technology,which is used by the transponder landing system based on MUSIC algorithm using virtual array,the causes and influencing factors of angle measurement error were analyzed. The author adopted and simulated a comprehensive error correction method combined with the actual. Simulation results show that this method can effectively solve the error,and shows good performance under low SNR. It also shows that the method has a high reliability.
