Sustained Japanese radar research from 1936

What if the Imperial Japanese Navy consistently funded radar development from 1936?

A substantial amount of radar could have entered service by 1941 if funding stayed consistent and researchers achieved roughly comparable breakthroughs.

The counterfactual assumes consistent support for Japanese aircraft-detection and VHF radar work beginning in 1936. Its premise includes Doppler-interference detection experiments and a split-anode magnetron operating at wavelengths down to about 12 cm. Research paths never followed are difficult to predict. Comparison with contemporary programmes suggests the possibility of substantial radar deployment by 1941. That depends both on consistent funding and on roughly equivalent technical breakthroughs.
