In-vehicle pulse radar

An in-vehicle pulse radar, comprising a first printed circuit board for high frequency and a second printed circuit board for low frequency, and a connector connecting the two printed circuit boards;

• wherein the first printed circuit board includes:
• a local oscillator that outputs a local oscillation signal;
• a transmitting section configured to output a transmission signal by modulating the local oscillation signal inputted from the local oscillator;
• a transmitting antenna configured to receive the transmission signal from the transmitting section to emit to the air as radio wave;
• a receiving antenna configured to receive reflected waves of the radio wave reflected by an object;
• and
• a receiving section having a time division section that performs time division on a received signal received by the receiving antenna in synchronism with a measured distance, a frequency converter that converts a frequency of the received signal into a baseband signal, and a delay circuit that outputs the baseband signal by applying a predetermined delay time to the baseband signal;
• and
• the second printed circuit board includes:
• a signal processing section including an object information calculating section that receives the baseband signal from the receiving section via the connector to calculate information on the object, and a control signal generating section that outputs, via the connector, a control signal to the time division section for driving the time division section, wherein
• the delay circuit applies the delay time to the baseband signal so that the baseband signal output from the frequency converter passes through the connector by being delayed by a predetermined time from the control signal.
