Abstract
A radar system mounted on a vehicle includes a first radar and a second radar, each having a transmitter-receiver and a signal processor. The transmitter-receiver transmits radar waves to detect objects such as another vehicle or other obstacles. An operating cycle period T, Tand a transmission time X, Xduring which the radar waves are transmitted are set in both radars to satisfy the formula: K·TXXT≦(K+)·TXXunder a condition that TT, where K is a positive integer. By setting both radars in this manner, interference between two radars is avoided without using additional devices in the radar system, and a high detection accuracy is realized.
