The admiral tells Prof. Bickford and Karnes that the Thames is completely guarded by radar and that they can even see the fish, noting that nothing can get by the radar. However, radar uses microwave radio frequencies about a centimeter in length and microwaves are strongly absorbed by sea water within a few feet of transmission. Whilst the radar can see a destroyer and, later, Dr. Sampson's helicopter, it would be virtually useless underwater.
