现在的雷达都是在多脉冲观测的基础上进行检
测的,多个脉冲积累后可以有效地提高信噪比,从
而改善雷达的检测能力。积累处理可以在包络检波
前完成,称为检波前积累或者中频积累。信号在中
频积累时要求信号间有严格的相位关系,也就是说
信号是相参的,所以也称为相参积累。此外,积累
过程可以在包络检波后完成,称为检波后积累或者
视频积累。由于信号在包络检波后失去了相位信息
而只保留了幅度信息,所以检波后积累处理就不需
要信号间有严格的相位关系,因此这种积累又称为
非相参积累。实现非相参积累的方法有很多,例如
抽头延迟线积累(FIR 积累)器和反馈积累器。

状态空间方法建立的线性二自由度的车辆模型
说明: 通过状态空间方法建立了线性二自由度的车辆模型,然后通过转换,将状态空间转换成传递函数的形式,能看到速度变化后,质心侧偏角和横摆角速度的变化趋势。(The vehicle model with linear two degrees of freedom is established by the state space method, and then the state space is transformed into the form of transfer function through transformation. After the speed changes, the change trend of the sideslip angle and the yaw rate of the center of mass can be seen.)
