ANALOG-DIGITAL CONVERTER MODULE Russian patent published in 2006 - IPC G01S13/02 

FIELD: engineering of receiving routes for radiolocation or analogical systems.

SUBSTANCE: analog-digital converter module contains two channels for digital processing of signal, each one of them consisting of differential signals generator, analog-digital converter, digital quadrature generator, digital heterodyning generator, permanent recording device, digital adder, optimal filter, multiplexer and controller of low voltage differential information transfer line, also, module includes digitization frequency generator and control device common for both channels for digital processing of signal.

EFFECT: expanded dynamic range, increased precision of transformation of broadband analog signals in series of digital counts, generation of real and imaginary quadrature components of digitized signals from the output of each one of receiving channels of onboard radiolocation station, preparation of primary information about detected objects and objects being tracked and return of it to control systems of radiolocation station.
