摘要： A radar device capable of removing noise signals before digital conversion and detecting an object with high precision by a simple configuration is provided. In a transmitting RF unit 110, a signal switch 141 is switched so that the noise signal generated by the operation of a first switch 111 passes through a signal delaying device 142. The signal switch 141 is switched so that the noise signal generated by the operation of a second switch 112 passes through a signal delaying device 143. Furthermore, the signal switch 141 is switched so that a baseband pulse signal obtained when the first switch 111 and the second switch 112 are operated at the same time passes through a signal delaying device 144. In a signal synthesizer 145, synthesizing is carried out so that the noise signals mixed in pulse signals are cancelled out.

摘要： There is provided an in-vehicle pulse radar that permits to detect information on an object accurately by temporally separating a noise signal mixed into a receiving signal by applying a delay time with a simple configuration. A baseband signal down-converted by a frequency converter (152) is output to a signal processing section (102) through a board-to-board connector (103) after passing through a delay circuit (153). Still further, a control signal is output to a switching circuit (151) from a control signal generating section (162) through the board-to-board connector (103). The delay circuit (153) increases a time lag from when the control signal passes through the board-to-board connector (103) until when the baseband signal passes through the board-to-board connector (103) by applying a predetermined delay time to the baseband signal. Thereby, the baseband signal receives no interference from the control signal.
