Abstract:
1. Digital cueing radio receiver apparatus comprising the combination of: an analog-to-digital converter circuit having an input port connected to a source of microwave frequency analog signals; a digital memory circuit connected with an output signal of said analog-to-digital converter circuit and having data storage capacity for a selected interval of digital converted microwave frequency analog signal input data words; a wideband monobit radio receiver connected with an output port of said digital memory circuit and including an embodied input frequency identification Fourier transformation algorithm having a selected limited number of unit magnitude-related approximated Kernel function values; and a narrowband fine tuned radio receiver having a signal input port connected with an output port of said digital memory circuit and a tuning frequency control input connected with an output signal of said wideband monobit radio receiver; said narrowband fine tuned receiver generating at least one of a frequency identification output signal, an input signal time of arrival identification output signal, an input signal pulse width identification output signal and an input signal pulse amplitude identification output signal.
