Backend components for noise radar and techniques for operation of those components are provided. Some embodiments include noise radar apparatuses. A noise radar apparatus may include a first unit that generates a random signal or a broadband noise signal using asynchronous logic gates constituting the first unit. The noise radar apparatus also may include a second unit that generates a reference sequence using the generated random signal or the generated broadband noise signal. The second unit comprises at least one tapped delay line formed by second asynchronous logic gates having sampling functionality and storage functionality. The noise radar apparatus may further include a third unit that receives a return signal correlates the return signal and the reference sequence in nearly real-time using third asynchronous logic gates constituting the third unit.
