VEHICLE-BORNE RADAR SYSTEMS WITH CONTINUOUS-TIME, SIGMA DELTA ANALOG-TO-DIGITAL CONVERTERS, AND METHODS OF THEIR OPERATION |
摘要 |
PROBLEM TO BE SOLVED: To provide vehicle-borne radar systems, and methods of their operation.SOLUTION: The vehicle-borne radar system includes a transmit path and a first receive path. The transmit path is capable of producing a signal for transmission over an air interface (e.g., a frequency modulated continuous wave (FMCW) signal). The receive path includes a continuous-time (CT) sigma delta analog-to-digital converter (ADC), and the receive path is capable of receiving a reflected version of the signal from the air interface, and converting the reflected version along the receive path into a sequence of digital samples using the CT sigma delta ADC. In an embodiment, the transmit path and the receive path are integrated onto a single integrated circuit. |
