雷达系统使用说明（The English instructions are located in the lower half of the article.）

一、基础配置

1. 雷达参数设置
   
   
   
   • 最大探测距离：通过修改
     
     "Maximumdetectiondistancekm" 变量（单位：公里）设置雷达探测范围，默认值为 150公里。
   
   
   • 屏幕分辨率：
     
     "Screenresolution" 指MFD的每平方米像素数（默认1024像素）。数值越高，细节越清晰但可能影响性能。
   
   
   • 屏幕尺寸：
     
     "Screenlengthm" 和 "Screenwidthm" 为MFD的物理尺寸（默认0.23米×0.23米）。
   
   
   • 探测角度：
     
     "Radardetectionangle" 设置雷达扫描扇区角度（默认90度），之后会重置为"Radardetectionangle/2" 用于计算半角。
   
   
   • 公制单位系统：所有测量均使用公制单位
   
   
2. 界面元素
   
   
   
   • 中心标签：显示当前航向，动态更新飞行方向。
   
   
   • 距离刻度：以同心圆形式显示距离标记（如150km、100km、50km），颜色为绿色。
   
   
   • 半角辅助线：两条绿色直线标示雷达半角边界（默认45度）。
   
   

二、操作流程

1. 启动雷达
   
   
   
   • 触发
     
     进入游戏后后，检测到AG1由关闭变为开启状态时开始初始化，直到初始化完成（状态变量 "Radarinitializationstatus" 变为"True"）。
   
   
   • 初始化完成后，雷达界面（MFD纹理）将在中心位置生成。
   
   
2. 实时探测
   
   
   
   • 雷达每帧更新一次，检测周围飞机（通过 "Identified_aircraft" 列表管理）。
   
   
   • 检测条件：
     
     
     
     
     
     • 目标飞机非玩家操控（"Craft.IsPlayer=False"）。
     
     
     
     • 目标位于雷达扇区内且距离小于最大探测值。
     
     
     
   
   
3. 目标标注
   
   
   
   • 检测到的飞机会在雷达上显示为绿色圆标记，标签包含：
     
     
     
     
     
     • 飞机名称（如 "Aircraft-Label-name"）。
     
     
     
     • 高度、速度、距离信息（如 "Height: 3000m <br> Speed: 800km/h <br> Distance: 25km"）。
     
     
     
   
   
   • 若目标速度超过5m/s，会显示速度矢量线。
   
   

三、交互与调试

1. 故障排查
   
   
   
   • 若雷达无显示，将AG1重启即可。（AG1关闭时自动清空内容，AG1再次开启时将重新初始化）
   
   

Radar System User Manual

I. Basic Configuration

1. Radar Parameter Settings

   • Maximum Detection Range: Set the radar detection range by modifying the variable "Maximumdetectiondistance_km" (unit: kilometers), with a default value of 150 kilometers.
   • Screen Resolution: "Screen_resolution" refers to the number of pixels per square meter of the MFD (default: 1024 pixels). Higher values yield clearer details but may impact performance.
   • Screen Size: "Screenlengthm" and "Screenwidthm" represent the physical dimensions of the MFD (default: 0.23 meters × 0.23 meters).
   • Detection Angle: "Radardetectionangle" sets the radar scan sector angle (default: 90 degrees), which is later reset to "Radardetectionangle/2" for calculating the half-angle.
   • Metric System: All measurements use the metric system.

2. Interface Elements

   • Center Label: Displays the current heading and dynamically updates the flight direction.
   • Distance Scale: Shows distance markers (e.g., 150km, 100km, 50km) in concentric circles, colored green.
   • Half-Angle Auxiliary Lines: Two green straight lines indicating the radar half-angle boundaries (default: 45 degrees).

II. Operating Procedures

1. Starting the Radar

   • After entering the game, initialization begins when AG1 is detected switching from off to on, continuing until completion (the status variable "Radarinitializationstatus" becomes "True").
   • Upon initialization completion, the radar interface (MFD texture) will be generated at the center position.

2. Real-Time Detection

   • The radar updates once per frame to detect surrounding aircraft (managed via the "Identified_aircraft" list).
   • Detection Conditions:
   • The target aircraft is not player-controlled ("Craft.IsPlayer=False").
   • The target is within the radar sector and its distance is less than the maximum detection value.

3. Target Annotation

   • Detected aircraft appear as green circular marks on the radar, with labels containing:
   • Aircraft name (e.g., "Aircraft-Label-name").
   • Height, speed, and distance information (e.g., "Height: 3000m <br> Speed: 800km/h <br> Distance: 25km").
   • If the target’s speed exceeds 5 m/s, a velocity vector line will be displayed.

III. Interaction and Debugging

1. Troubleshooting

   • If the radar does not display, simply restart AG1. (When AG1 is turned off, content is automatically cleared; when AG1 is turned on again, it will reinitialize.)
