Abstract:
A method for transceiving radar signals and a radar apparatus applying the same are provided. The radar apparatus scrambles order of a plurality of serve frequency substitution by dividing frequency of specific substitution to a signal transmission into a plurality of the serve frequency substitution, and transceives the signal transmission for the serve frequency substitution in scrambled order, thereby determining the signals by using the scrambled order. According to the method, in a case of using a multiple of radar when the radar frequency substitution is limited, obtaining wrong radar information by an interference signal between each other and a ghost signal about a nonexistent target are able to be prevented.

Abstract:
PURPOSE: An RF(Radio Frequency) transceiver is provided to minimize interference and leakage of a signal by adding impedance between signal ports. CONSTITUTION: An RF signal port(510) outputs a first signal of an RF band. An IF(Intermediate Frequency) signal port(540) receives a second signal of an IF band. An LO(Local Oscillator) signal port(530) outputs an LO signal. A mixer(520) converts the first signal outputted from the RF signal port into the second signal by mixing the LO signal with the first signal outputted from the RF signal port. The mixer outputs the second signal to the IF signal port. [Reference numerals] (510) RF signal port; (530) LO signal port; (540) IF signal port
Abstract:
PURPOSE: A sensor compensation system using video information and distance-angular information is provide to restructure the coordinates of the real world by using distance information obtained through output of a distance-angle sensor, and to automatically calculate a physical arrangement error in the distance-angle sensor and an image sensor. CONSTITUTION: An image sensor unit clearly recognizes an object from an input image. A distance-angle sensor unit extracts a rotation angle of the object by a laser. An information processing unit extracts the real location of the object. The information processing unit extracts the rotation angle of the object according to the extracted real location. The information processing unit outputs an error compensation signal. The error compensation signal directs the difference between the extracted rotation angles within a predetermined range.
