Abstract
The detector of the present invention includes a first and a second signal channel each of which is adapted to receive a spread spectrum signal, or any other similar type multi-modulated carrier signal. In the preferred embodiment of the invention, the first signal channel is provided with a correlator for partially demodulating the received signal, as to one modulation signal component, with a demodulation signal derived from the second signal channel. The first signal channel is also provided with an additional correlator for demodulating the partially demodulated signal as to another modulation component. The second signal channel is comprised of a means for generating a dithered demodulation signal which signal is driven into synchronization with a corresponding modulation signal component in the received signal so as to enable the accurate generation of the demodulation signal utilized by the first signal channel.
