Title:

IN-CAR PULSE RADAR

Document Type and Number:

WIPO Patent Application WO/2011/122268

Kind Code:

A1

Abstract:

Provided is an in-car pulse radar capable of detecting an object information with high accuracy while preventing the noise signal from being mixed into a received signal by providing a delay time to separate both signals time-sequentially with a simple configuration. A base band signal which is down-converted by a frequency converter (152) is outputted to a signal processing part (102) via a board-to-board connector (103) after passing through a delay circuit (153). Further, a control signal is outputted to a switch circuit (151) from a control signal generating part (162) via the board-to-board connector (103). The delay circuit (153) increases the time difference from the time when the control signal passes through the board-to board connector (103) to the time when the baseband signal passes through the board-to-board connector (103) by providing a given delay time to the baseband signal. Thus, the baseband signal is not subjected to the interference from the control signal.
