| 摘 要： | 利用贝塞尔函数，经过计算推导得到三角波调频测距引信回波信号的数学模型。用VC 实现系统仿真，把仿真结果与实测数据进行比对，验证系统仿真数学模型的正确性。对仿真得到的二次、四次回波多普勒信号取其包络，分析炸高分布情况，验证调频引信定距高度不受落速、反射系数N(不同地形背景)和弹着角的影响。

| Abstract: | In this paper, firstly we give the math model of the harmoric signal of a triangle-wave FM distance meauring fuze through calculating and deducing using bessel function. Then we make the system simulation by utilizing VC++, compare the simulated result with real data to validate the correctness of the math model, and utilize the envelope of two and four harmonic poppler signal from simulation to analyze the distribution of burst point height of the fuze. Results indicate that the burst point height of the FM fuze is in depandent of the falling velocity, different terrain background reflection factor N and projectile impact velocity. |
