摘要: 該文分析了連續(xù)波雷達(dá)參差多頻測(cè)距算法的局限性,提出了多頻連續(xù)波雷達(dá)的兩種測(cè)距算法,即多頻到雙頻測(cè)距法和二次相差法,并介紹了它們的基本原理。最后對(duì)兩種方法進(jìn)行了對(duì)比,并進(jìn)行了仿真。仿真結(jié)果表明, 兩種測(cè)距算法都達(dá)到了比較高的測(cè)距精度,在最后雙頻對(duì)應(yīng)的最大不模糊距離相同的基礎(chǔ)上,兩種算法的測(cè)距精度相當(dāng)。

Abstract: This paper analyses the limitation of the algorithm of stagger multiple frequency for CW radar, and two algorithms are proposed.They are the algorithm of multiple frequency to dual frequency and the algorithm of quadratic phase difference.Their principles are introduced. Finally, two algorithm are compared with each other, simulation result is also given.The simulation result shows that two algorithms both reach high ranging accuracy.They have equivalent ranging accuracy if their maximal unambiguous ranges of the last dual frequency are the same. -
