No, that's just wrong ... Radar was in it's infancy when the war began and was just starting to achieve long range ship board reliability by the war's end. The mark 1 eyeball was the Navy's main detector system and remained in use 24 hr's a day thru the end of the war
In 1940 the radar was in its infancy, by 1944-45 every American CV was sporting an SK Radar set with a 130 ft. antenna that could pick out large planes at 250,000 yards (142 miles) and small planes at 150,000 yards (85 miles). The radar set was not the problem, it was the curvature of the earth that became the limiting factor, which is why they put radar sets on destroyers and sent them out as pickets over the horizon to increase their coverage.
WW2 radar operators manual is HERE:
http://hnsa.org/doc/radar/part4.htm#pgSCSK-1What we need generally in AH and specifically for the CVs is a larger radar range. By the time I break a 12 mile radar circle in B26s at 280 knots, you have less than 3 minutes to up, climb and intercept before I drop my bombs. Usually the ONLY thing that gets me is the AAA, and that usually after I have already dropped, so bye bye CV.
CV radar range should be tripled to 36 miles, and the radar should distinguish between large (buff) and small (fighter) targets. Large Airfields should get this as well.
Medium Airfields should get a 24 mile range, and leave the Small Airfields and V-Bases at 12 mile radar range.
