ABSTRACT:
An acousto-radio frequency modulator and an apparatus employing the same are disclosed. The acousto-radio frequency modulator includes a radiowave waveguide including a first end defining an input and a second end defining an output; an acousto-radio material positioned in the signal path of the radiowave waveguide; and a acoustic source coupled to the acousto-radio material and capable of driving an acoustic signal through the acousto-radio material. The apparatus includes a plurality of ARFMs, each capable of modulating a component of a received RADAR signal received by the antenna; a frequency combiner capable of frequency multiplexing each of the components into a combined signal; a filter capable of filtering the combined signal; an amplifier capable of amplifying the filtered signal; and an analog to digital converter capable of converting the amplified signal to a digital representation.
