摘要： PURPOSE: A frequency modulated continuous wave (FMCW) radar system using an adaptive scheduler is provided to improve a multi-target resolution in complex road environments or in the low speed driving of a vehicle. CONSTITUTION: An FMCW radar system (10) comprises a transceiver (100), a signal processor (200), and a scheduler (300). The transceiver responds to a chirp inclination control signal, a multi-waveform control signal, and a renewal time control signal; frequency-modulates a triangular wave which tidally sweeps into a linear shape in order to transmit; and receives a reflected signal from a target. The signal processor produces a chirp inclination control signal, a multi-waveform control signal, and a renewal time control signal to transmit to the transceiver according to a chirp inclination, the number of multi-waveforms, and a renewal time. The signal processor estimates the speed and distance of the target by mixing a signal transmitted after the frequency-modulation with the reflected signal and producing a beat frequency. The scheduler determines a chirp inclination, the number of multi-waveforms, and a renewal time about the transmitting signal of the next period based on the speed and distance information of the target and the speed information of a current vehicle received from a vehicle sensor to transmit the determined result to the signal processor.

摘要： PURPOSE: A receiver of radar for a vehicle and a directional arrival angle estimation method thereof are provided to control the increase of calculation amount without increasing a correlation matrix. CONSTITUTION: A receiver receives multiple reception signals through a plurality of reception channels (S10). The signal path of each reception channel processes a downlink frequency, the reception of a digital signal, fast Fourier transformation, and calibration (S20). A signal processor of the receiver calculates a correlation matrix indicating the location of a target in a chirp pulse (S30). The signal processor of the receiver executes correlation matrix equalization in order to estimate a noise area in the calculated correlation matrix (S40). The signal processor of the receiver divides the equalized result of the correlation matrix into a signal area and a noise area (S50). The signal processor of the receiver selects the number of targets from a signal area excluding the noise area from an eigenvector (S60). The signal processor of the receiver estimates a directional arrival angle for the selected target (S70).

摘要： PURPOSE: A vehicle radar apparatus using an arrayed antenna for detecting vertical directions and a detecting method of the same are provided to easily recognize clutter in the vertical direction of the front side of the apparatus. CONSTITUTION: A receiving arranged antenna(122) includes an azimuth channel and a vertical channel. If a radar signal radiated from a transmitting arranged antenna(121) is reflected from obstacle at the front side of an apparatus, the azimuth channel receives the reflected radar signal. If a radar signal radiated from the transmitting arranged antenna is reflected from obstacle at the front vertical side of the apparatus, the vertical channel receives the reflected radar signal. A signal comparator(140) compares the sizes of the radar signals of the azimuth channel and the vertical channel. If the size of the radar signal of the vertical channel is larger than that of the azimuth channel, the existence of the clutter is verified by a signal analyzer(150).
