Abstract: PURPOSE: An accuracy comparing system and a method of target detecting sensor is provided to minimize the amount of time consumed and the cost for comparing the accuracy of the target detecting sensor. CONSTITUTION: An accuracy comparing system of target detecting sensor comprises a target sensing sensor(100), a first and a second camera(210,220), a time code generator(300) and a control device(400). A first and a second camera shoots the targets and generate a first and a second image respectively according to the photography result. A time code generator outputs a time code to coincide the measurement time of the detected information with a first and second image. A control device squares the detected information with a first and a second image of the spatial coordinated system and generates a 3D position data of the target using the corresponded spatial coordinate system with the first and second image. A control unit squares the 3D position data and the temporal coordinate system using a received time code from a time code generator and outputs the accuracy of the target detecting sensor by comparing the 3D location information which has unified the space and time with the detected information.

Abstract: PURPOSE: A high-speed image formation method and a high-speed image formation device for a bistatic radar are provided to increase an image processing speed without degrading the image quality of a radar by transceiving electromagnetic waves through a bistatic technique and by performing a dechirping process. CONSTITUTION: A signal processing unit receives dechirped data Sr{ta, te} from a data conversion unit(S110) and performs a fast Fourier transform on the dechirped data in the azimuthal direction(S120). RCMC(Range Cell Migration Correction) is performed for compensating for the difference of a distance cell from the center of a radar observation point in a distance-time domain using a frequency scaling function for the converted Sr{fa, te}(S130), and SRC(Secondary Range Compression) is performed for additional compression(S140). Afterward, the signal processing unit performs a fast Fourier transformation on the data completed with the RCMC and the SRC in the distance direction(S150), and performs the azimuthal angle scaling on the converted data into a distance-frequency domain using a frequency scaling function(S160). Finally, the signal processing unit performs an inverse fast Fourier transformation on the azimuthal angle scaled data in the azimuthal direction(S170).

Abstract: PURPOSE: An RF signal input device and method are provided to minimize an error resulting from environmental influence and fixture manufacturing and to enable phase alignment between channels of a radar interferometer and gain correction between channels. CONSTITUTION: An RF signal input device(100) for performance verification and correction of a radar interferometer includes an RF signal generator(110), a 1:N signal distribution part(130), multiple phase shifters(140), an adaptor(150) and a control part(180). The RF signal generator generates an RF signal synchronized with a radar interferometer. The 1:N distribution part distributes an RF signal to correspond to the number of reception channels of a radar interferometer by receiving an RF signal synchronized with a radar interferometer. Multiple phase shifters access every output of the 1:N distribution part to adjust the phase of each RF signal output from the 1:N distribution part. An adaptor separately inputs N RF signals output from each phase shifter to N reception channels by accessing N phase shifters with each reception channel of the radar interferometer. A control part controls adjustment of the phase value in the phase shifter to align phase of each RF signal output from the adaptor.

Abstract: PURPOSE: A front observation 3D image radar apparatus and a 3D image acquiring method using the same are provided to form a transmitter/receiver by independently applying a receiver according to a receiving antenna. CONSTITUTION: A transmission unit(110) creates a radio frequency signal which is emitted for the observation of a front object. Transmission antennas(120a,120b) radiate the radio frequency signal which is created by the transmission unit to outside. A receiving antenna receives a signal which is reflected from the front object about the signal which is emitted from the transmission antenna. A receiver(140) forms a digital signal by mixing the signal which is emitted from the transmission antenna and a transmission signal from the transmission unit. A signal processing unit(150) controls an operation of the transmission unit and the receiver. The signal processing unit extracts phase information about the front object from the digital signal. The signal processing unit creates advanced information and a three-dimensional radar image.
