Improving radars gives more accuracy and LOS.

If you don't have it yet, the iwamoto quest chain starts with a Type zero model 21 (skilled), so you can start by improving these.

For unryuu, she has a drop rate of 0.678% in 6-3 with S rank (doesn't appear in A rank). I thought it was not recommended to farm there, but i don't remmember how hard was the map, so i can't really tell.
