To evaluate when RADAR is effective, let's analyze the given conditions.

1. **Fog**: RADAR can penetrate fog as it uses radio waves, which are less affected by moisture in the air compared to light waves.

2. **Smoke**: RADAR can also operate effectively in smoky environments, as smoke does not significantly obstruct radio waves.

3. **Night**: RADAR functions equally well at night since it does not rely on visible light; it uses radio waves which can detect objects regardless of the time of day.

Since RADAR is effective under all of these conditions (fog, smoke, and night), the statement "All of the options are correct" is indeed true.

### Final Answer
**All of the options are correct.** RADAR is effective in fog, smoke, and at night.
