## 末敏弹参数调整

|

调整参数后的运行记录
|
||||
|
||||
| 精度 | 角度误差 | 仿真步长 | 视场角 |
|
||||
| ------ | -------- | -------- | ------ |
|
||||
| 0.73米 | +1.08 度 | 0.0005秒 | 0.2度 |
|

| 0.32米 | +0.36 度 | 0.0005秒 | 0.5度 |

|

|
||||
| 36.14米 | +34.20 度 | 0.02秒 | 5度 |
|
||||
|
||||
从以上数据可以看出，仿真步长越小，精度越高，角度误差越小，视场角越大，探测距离越远。
|
||||
最好的参数是：
|
||||
|
||||
- 仿真步长：0.0005秒
|
||||
- 视场角：0.5度
|
||||
- 精度：0.32米
|
||||
- 角度误差：+0.36度
|
||||
|
||||
比较合理的参数是：
|
||||
|
||||
- 仿真步长：0.001秒
|
||||
- 视场角：1度
|
||||
- 精度：1.62米
|
||||
- 角度误差：+0.36度
