摘要
以战车主动防护系统为背景,针对双频连续波、相位编码连续波和线性调频连续波3种连续波信号形式,单独使用都无法满足战车主动防护系统中目标距离近、速度快、回波信号功率低的特殊要求,提出了一种点频加负斜率调频连续波的组合信号形式。仿真结果表明,此种组合信号形式可以正确解出高速目标情况下的目标信息.
Literarily, dual frequency continuous wave, phase coded continuous wave and linear frequency modulated continuous wave were introduced to the vehicle active defense system. While the defense system concerns about high-speed target with small radar cross section which emerges at an ultra- short range, the result shows that simple signals cannot satisfy the demands. A suitable hybrid signal composed of continuous wave and linear frequency modulation continuous wave is proposed to make use of the vehicle active defense system. Simulation result shows that this hybrid signal can obtain correct information of a high-speed target.
