I'd say
and please I would like to be challenged on that..
the design inherent deficits of inflight wx radar cannot be and have not been adressed by the new technology we have nowadays, at least not to any measurable extent..
there have been good radars 30 years ago, I fondly remember a Primus 400 in a Falcon 20 in the early 80's..(high powered cloud slicer)
nowadays I look at an also very good modern Primus WX-880 in a Falcon 900EX..(again high powered cloud slicer)
magnetron based radars in short..
In between in the 90's I have seen some, at least in my humble opinion, horrible aberrations in WX radar design, from all manufacturers , in all kinds of different birds..(mostly "low-powered flash lights" whose limitations have been further emphasized by bad quality (read that as low transmissivity) radomes..
