基于matlab粒子滤波的雷达弱小点目标检测
PyART是一个用Python编写的雷达分析工具包,可用于读取、处理和可视化雷达数据。要查看雷达格点,请按照以下步骤操作:
1. 导入必要的模块:
```python
import pyart
import matplotlib.pyplot as plt
```
2. 使用pyart.io.read_nexrad_archive读取雷达数据,如下所示:
```python
radar = pyart.io.read_nexrad_archive('/path/to/nexrad/data')
```
3. 获取雷达扫描的格点数据,如下所示:
```python
grid = pyart.map.grid_from_radars(
radar,
grid_shape=(1, 241, 241),
grid_limits=((2000, 2000), (-123000.0, 123000.0), (-123000.0, 123000.0)),
fields=['reflectivity'],
weighting_function='Barnes2',
gridding_algo='map_gates_to_grid',
roi_func='constant',
constant_roi=500.0
)
```
4. 使用pyart.graph.GridMapDisplay.plot_basemap()和pyart.graph.GridMapDisplay.plot_grid()可视化雷达格点,如下所示:
```python
display = pyart.graph.GridMapDisplay(grid)
display.plot_basemap()
display.plot_grid('reflectivity')
plt.show()
```
