摘要
A multichip radar system is disclosed, comprising a plurality of configurable ICs, and a digital interface therebetween, each configurable IC being configurable to operate as a master IC and as a slave IC. The configurable lCs may be similar or identical, and have an allocated measurement range. Each configurable IC comprises: a down-converter; an ADC; a digital signal processor; and a transmitter to transmit a radar signal. One is configured as a master IC and to transmit a radar signal and each of the other configurable lCs to operate as a slave IC. Each configurable IC is adapted to use a common Local Oscillator signal, a common clock signal, and a common timing signal for determining at least the start of the common sampling window. A method of operating such a multichip radar system is also disclosed, as is a configurable IC or radar IC suitable for such a system.
