Detection and location of very low flying aircraft is often impossible or at least very difficult to achieve by radar. The idea of filling this detection gap by making use of the acoustic noise radiated from an aircraft is considered. Some general thought is given to the problem of acoustically measuring parameters of targets that move with speeds close to sonic speed. Some preliminary experiments allow a rough estimate of the detection range and bearing measurement errors to be made.
