RADAR JAMMING: Searching the skies for Japanese radar signals required specialized electronic equipment, which was installed in designated aircraft. The equipment included a) a tuner-analyzer to measure the Japanese radar frequencies and strength and presumably the pulse width and pulse repetition frequency and b) four to five transmitters producing static noise, in effect jamming the Japanese radar signals. Based on this information, one could determine whether the signals were emitted by gun laying radar or radar-directing searchlights or air-to-air radar in Japanese fighters. The radar countermeasures observer also observed the coincidence of enemy signals with enemy action and the weather. What was not observed was just as important. The Japanese night fighters had no airborne radar. In a few cases, they were observed to have air-to-surface vessel type radar. The Japanese radar operated on 75 and 200 megahertz bands but no 540-megahertz band radar was observed.
