Why cant you use Low Range altimeter principle for Weather Radar detection?
Your question is a bit confusing. I’d assume you meant “weather detection”. And it would have been better if you had mentioned what is “altimeter principle”. I’d point out one major difference in the processing of weather echoes and point target echoes as in a radar altimeter. For the point target the radar return is assumed to have bounced off a single point. For weather, it is bounced off a volume in space. So the strength of echoes vary and hence the processing. We can talk of radar bands and other stuff if you could give more details.
