# ===================== 创建画布 =====================
fig, ax = plt.subplots(figsize=(8, 8))
ax.set_xlim(-100, 100)
ax.set_ylim(-100, 100)
ax.set_aspect("equal")
ax.grid(True, alpha=0.3)
ax.set_title("航迹与雷达覆盖动态展示")
ax.set_xlabel("X")
ax.set_ylabel("Y")

# 绘制雷达站点
radar_point, = ax.plot(radar_x, radar_y, "ro", markersize=8, label="雷达站")

# 航迹：完整轨迹线 + 当前位置点
track_line, = ax.plot([], [], "b-", linewidth=1.5, label="历史航迹")

# 雷达扇形覆盖（Wedge楔形）
wedge = Wedge((radar_x, radar_y), radar_range, scan_start_angle, scan_start_angle,
width=radar_range, color="orange", alpha=0.3)
ax.add_patch(wedge)

ax.legend(loc="upper right")

# ===================== 动画更新函数 =====================
current_scan_angle = scan_start_angle

def update(frame):
global current_scan_angle
# 1. 更新雷达扫描扇形结束角度
current_scan_angle += scan_speed
# 扫描到头后折返
if current_scan_angle > scan_end_angle:
current_scan_angle = scan_start_angle

wedge.set_theta1(scan_start_angle)
wedge.set_theta2(current_scan_angle)

# 2. 更新航迹：绘制到当前帧为止的轨迹
idx = min(frame, total_points - 1)
track_line.set_data(track_x[:idx+1], track_y[:idx+1])
track_now.set_data(track_x[idx], track_y[idx])

return track_line, track_now, wedge

# ===================== 启动动画 =====================
ani = FuncAnimation(
fig, update, frames=150, interval=50, blit=True
)

plt.show()
# 如果需要保存视频，取消下面注释（需要ffmpeg）
# ani.save("radar_track.gif", writer="pillow", fps=20)
运行结果如下：
