Determination of Ship Course and Speed from Transmitted Signal Frequency.

Abstract

In the design of the C/P Array Sonar, some consideration is being given to the use of an own-doppler-nullifier technique in which the transmitted frequency is varied according to the speed of the sonar vessel and the direction of the transmitted beam. The objective here is merely to determine if transmitting a frequency which is a function of own ship's course and speed furnishes a valuable additional clue which might enable the enemy submarine to calculate the surface vessel's course and speed. It is not the purpose of this paper to evaluate the merits of the proposed own-doppler-nullifier technique as they apply to signal processing aboard the surface vessle.
