Asubmarine is attempting to detect an aircraft carrier transiting the straits of malacca. the aircraft carrier has a source level of 90 db. the submarine's passive sonar has a directivity index of 20 db and a detection threshold of 15 db. biological noise in the straits is 54 db. the submarine's self noise is 50 db. given that tl = 10 log r, where r is the range in yards (we will show you where this comes from soon), at what range can the carrier just be detected?
