| (M) | RADAR (Continued) - |
| Contact #1 | Seven miles south of Lombok Strait picked up radar. Antenna rotation was not constant. There were two minor lobes either side of a major lobe. Major lobe trained on us for about 15 seconds at a time. |
| Contact #3 | This 10 cm interference came from a man of was, probably the heavy cruiser. It's pulse width was longer than the SJ's. The pulse rate is either the same as ours (1600 cps) or a harmonic. The interference was strong but we could pick it up till we closed in to 17,000 yards. The radar was being keyed with rather long intervals of silence. "On time" was not timed due to circumstances. Their beam width was very narrow, approximately 5 degrees indicating that it is being used as fire control. On the SJ's "A" scope the interference is very similar to SJ interference. So much so that at first we mistook it for same. Contact made on PPI. Unable to get anything on APR. |
| Contact #5 | At the approaches of the narrows going through the Lombok Strait we encountered interference from Bali, Lombok and Noesa Bosar. No definite information was obtainable. APR had no contact and on the SJ it merely increased the grass. Beam width on the PPI was approximately 7 degrees. Interference was received from the southern end of Bali. Transmission lasted 1 minute then Noesa Bosar transmitted for 1 minute after which Lombok transmitted for 1 minute then the cycle repeated itself. |
