摘要
通过对连续波双频测距与多频测距基本原理的分析,针对双频测距存在最大不模糊距离与测距精度相互矛盾的局限性,并考虑到多频测距对正确解模糊所需信噪比较高这一缺点,同时结合双频测距与多频测距的优势,提出了一种从多频到双频转换的连续波测距新方法。文中对这种新方法的测距步骤进行了详细论述,并进行了仿真分析,仿真结果证明了该方法的有效性。
By analyzing the basic principle of dual frequency CW ranging radar and multiple frequency CW ranging radar, a new approach to improve performance of CW ranging radar is presented. The new approach widely uses the advantage of dual frequency CW ranging radar and multiple frequency CW ranging radar, solves the localization in enlarging maximum unambiguous range while improving ranging accuracy for dual frequency CW ranging radar, and overcomes the shortcoming in requiring higher SNR for multiple frequency CW ranging radar. This paper gives the ranging steps of the new approach in details. The simulation results verify the validity of the new approach.
