ABSTRACT:
In a signal transmission system for broadband signals wherein the transmitting transducer and/or the receiving transducer has a non-isotropic radiation characteristic, properties of the received broadband signal, for example waveform shape, spectrum, duration and probability density function, depend on the alignment orientation of the transducers. A discriminator circuit is provided in the receiver for identifying or estimating parameters related to one or more of such properties as a measure of alignment orientation of the transducers. The invention can be utilized, for example, in noise-suppressing radio frequency message transmission systems wherein band spreading modulation (spread-spectrum-system) results in transmission of a much greater bandwidth than a conventional transmission of the message baseband frequencies.
