中文摘要	随着战争形态的升级,精确制导武器在战争中所发挥的作用越来越突出。引信作为精确制导武器的最终环节也越来越受到重视,而抗干扰性能更是决定整个精确制导武器最终能否形成杀伤力的重要因素。由于引信工作环境特殊性和测距性能需要,调频连续波引信逐渐发展并成为了引信常用体制之一。首先介绍了一种非线性调频连续波引信:单正弦调频连续波引信。然后对模糊函数进行了推导,得出了近似公式,绘制了模糊函数图,并与锯齿波调频连续波引信做出了对比分析,发现单正弦调频连续波引信在抗干扰性能方面要优于锯齿波调频连续波引信。最后对二者在受到噪声干扰时的测距性能进行了仿真,仿真结果验证了上述结论。; With the upgrade of war,the effect of precision-guided weapons becomes more and more significant in the war. As well,more and more attentions are paid to fuze as the final part of precision-guided weapons. Its anti-jamming performance is an important factor determining whether the precision-guided weapons can eventually form lethality. Due to the particularity of fuze working environment and ranging performance demands,the FM-CW fuze gradually develops and becomes one of the common systems of the fuze. First of all,a single-sinusoidal FM-CW fuze was introduced. Then its ambiguity function was derived,and the approximate formula as well as the ambiguity function diagram was obtained. A comparative analysis was made with the sawtooth FM-CW fuze. The advantage in anti-jamming performance of single-sinusoidal FM-CW fuze was discovered. Finally,the simulation of both ranging performance against noise interference was done,and the simulation results verify the conclusions above.
