摘要： A road surface detection apparatus capable of detecting an upward/downward displacement in radar axis when detecting a road surface by projecting a radar beam. The apparatus projects a radar beam signal onto the road surface on which the radar-equipped vehicle is traveling, and receives a signal containing a reflected signal of the radar beam signal. Then, the apparatus compares the level of the road surface reflected signal contained in the received signal with a predetermined reference level and, if the result of the comparison lies outside a predefined range, then the apparatus determines that the axis defining the projection direction of the radar beam signal is displaced.

摘要： An unwanted peak occurring due to an antenna sidelobe and an unwanted peak occurring due to a harmonic are eliminated in a radar apparatus. A peak from a target that can cause an unwanted peak is found based on the intensity of the peak, and a search is made for a peak having a predetermined positional relationship with the thus found peak. If such a peak is located, then it is determined whether the peak is a candidate for an unwanted peak, based on the difference between the intensity of the peak and the intensity of the main peak. If both of the paired peaks are determined as being candidates for unwanted peaks, it is determined that the peaks are unwanted peaks.

摘要： Provided is a signal processing apparatus configured to calculate an angle of a detection point corresponding to an object on the basis of received signals of a plurality of array antennas. A beat signal is generated by a difference between a transmitted signal and a received signal. Digital data is derived through AD conversion of the beat signal. The digital data is divided into a plurality of data groups. A fast Fourier transform is performed on the data groups to acquire a plurality of transformed data corresponding to the number of the data groups. The transformed data are divided into a plurality of sets, correlation matrices for the respective sets are acquired, and an average value of the correlation matrices is calculated. The angle of the detection point is calculated on the basis of the average value of the correlation matrices.

摘要： The occurrence of an axis displacement in a horizontal direction in a vehicle-to-vehicle distance controlling radar is detected, the amount of the axis displacement is determined, and an azimuth angle is corrected using the thus determined amount of the axis displacement. The frequency with which vehicle-to-vehicle distance control is released or re-set is measured and, if the frequency is higher than a threshold, it is determined that the axis is displaced. The amount of the axis displacement is determined from the angle of the locus of a stationary target. The azimuth angle of the target is corrected using the thus determined axis displacement angle.
