Map aware adaptive automotive radar

摘要

A dedicated short range radar system is provided for use with a GPS system. The radar system includes a transmitter which transmits a microwave radio signal. A receiver is coupled to a horizontally scanning receiver antenna array which receives an echo, if present, from the radio signal transmitted by the transmitter. The radio receiver then generates an output signal representative of the echo. A control circuit then receives the output signal from the antenna array as well as the output signal from the GPS system. The control circuit then varies the mode of operation of the receiver and/or the transmitter as a function of the type of roadway for optimal radar performance.

1. An automotive radar system comprising:
a GPS system which generates an output signal representative of the type of roadway, a transmitter which transmits a microwave radio signal, a horizontally scanning receiver antenna array, a receiver coupled to said horizontally scanning receiver antenna array which receives an echo, if present, from the radio signal transmitted by said transmitter and generates an output signal representative of the echo, a control circuit which receives said output signal from said antenna array and the output signal from the GPS system linked with a map database indicative of the type of roadway currently traveled by the automotive radar system, said control circuit varying the mode of operation of said receiver or said transmitter as a function of the type of roadway from the GPS system.
