A radar system for a motor vehicle is describe including a plurality (M) of transmitters for transmitting a radar signal, a receiver for receiving the transmitted radar signal reflected by an object, a signal re-constructor coupled to the receiver. Each transmitter is configured to transmit at least part of a frequency modulated continuous wave signal during a time period T having N sample time periods of duration T/N, and in each of the N sample time periods combinations of at least some of the transmitters transmit. The signal re-constructor is configured to determine the coordinates of an object with respect to the radar system from N measurements of the received frequency modulated continuous wave signal, each of the N measurements being made for a time period of T/N. The radar system may reduce the detection time for objects while maintaining the angular resolution.
A radar system for a motor vehicle comprising:
A method of determining the coordinates of an object in a radar system comprising a plurality of transmitters and a receiver, the method comprising transmitting at least part of a continuous wave signal during a time period by varying the combinations of the transmitters used to transmit the signal a number of sample times during the time period, receiving the transmitted frequency modulated continuous wave signal reflected from an object, and determining a distance and angle of the object with respect to the radar system from a number of measurements equal to the number of sample times.
