Effect of Front Wheel Turning Angle and Wheel Braking Status on Automotive Track Simulation

前轮转角和车轮制动状态对汽车轨迹模拟的影响

Basic concepts on "visual angle"," position angle"," inside track area"," outside track area" have been put forward.

提出了视角、位置角、轨迹区内、轨迹区外的基本概念；

Under the oppressive noise jamming, the seeker turns into the passive working mode of Homing on Jamming ( HOJ) from the initiative working mode. Monopulse radar seeker picks up the erro signal of the angle tracking, thereby, the seeker could track the target steady.

在压制式噪声干扰下，导引头由主动工作模式转为向干扰源寻的（HOJ）的被动工作模式，单脉冲雷达导引头可以从噪声干扰中提取出角跟踪误差信号，保持对目标稳定跟踪。

The first-order relative position equations are expanded as trigonometric series with eccentric anomaly as the angle variable. Except the terms of order one, the trigonometric series' amplitudes are geometric series, and corresponding phases are constant both in the radial and in-track directions.

通过将相对位置方程的径向和横向分量以偏近点角为变量展开为三角级数，发现除了一阶项外，三角级数的幅值为等比数列并且相角为定值。
