摘要： Generating an image matrix includes accessing a round-trip time matrix for a space having points. The round-trip time matrix describes an estimated round-trip time for a signal to travel from a transmit antenna, to a point, and to a receive antenna. Signals reflected from an object of the space are received at the receive antennas. The following are repeated for at least a subset of the points to generate an image matrix: select a point of the subset of points; for each receive antenna, establish a waveform of a signal received by a receive antenna and identify a waveform value of the established waveform that corresponds to the selected point according to the round-trip time matrix; and combine the waveform values for the selected point to yield an image value for the selected point. The image matrix is generated from the image values.

摘要： A system for processing electromagnetic waves in a radar system is disclosed. The system includes a transmitter operable to transmit operating waves and calibration waves, one or more receivers operable to receive reflected calibration waves and operating waves, and a system controller operable to process the received calibration waves and operating waves. The system controller may process the received waves by generating a threshold signal based on the calibration waves, and comparing the threshold signal to the operating waves. The system controller may also process operating waves and calibration waves in accordance with one or more signal conditioning algorithms. Additionally, the system controller may display an image representing a target on a display by comparing received operating waves with the generated threshold signal.
