1. An apparatus comprising a coherent radar system on a single chip that operates in a range of operation between approximately 0.1 terahertz and 1 terahertz, wherein the coherent radar system comprises a transmitter, the transmitter including:
a ramp generator electrically coupled to, and configured to provide a voltage signal to, a wide band voltage controlled oscillator;
a directional coupler electrically coupled to the wide band voltage controlled oscillator; and
a phased-array antenna electrically coupled to the directional coupler and configured to transmit high-frequency signals in the range of operation.
