How can heavy rain on the radar be mitigated?

Heavy rain on radar creates clutter that can obscure real targets, so the best mitigation is to apply rain clutter suppression and filtering, adjust the gain, and modify the scan angle, or wait for the weather to pass. Rain clutter suppression uses processing to separate meteorological echoes from potential targets, while filtering attenuates unwanted clutter and keeps the display readable. Tuning the gain helps maintain the radar’s dynamic range so rain doesn’t overwhelm the signal, and changing the scan angle can reduce the beam’s passage through the heaviest rain or shift clutter patterns away from important targets. If the weather is short-lived, waiting for it to pass removes the clutter entirely. Increasing the gain would amplify rain echoes and worsen clutter, ignoring the rain guarantees degraded performance, and switching to a different sensor isn’t the direct, real-time mitigation for rain-induced radar clutter.
