Abstract:
Examples of active millimeter-wave imaging systems are described which may utilize modulation schemes to provide illumination signals. The use of modulation techniques may allow for the use of direct-conversion receivers while retaining an ability to separate desired received signal from self-jamming and/or DC offset signal(s) generated by the direct-conversion receivers. In some examples, modulation schemes include the use of balanced orthogonal codes which may support MIMO or massive MIMO imaging systems.
