摘要： A scanning radar system accurately determines the lateral position of a target regardless of the heading of the target. The angle &PSgr; between the direction to the target and the heading of the target is calculated using equation &PSgr;=&thgr;−tan−1{d cos &thgr;/(R−d sin &thgr;)} and a correction value &Dgr;X for the lateral position X is determined based on the angle &PSgr;.

摘要： The invention detects a ghost occurring due to mispairing, reflections from a wall, or the like, and improves the ability of a radar to track targets when actual relative velocity changes by more than a certain value. If a stationary target is present within a prescribed region centered about a moving target, the stationary target is excluded from output data by determining it as being a target resulting from mispairing due to the detection of guardrail posts or similar structures. Further, a moving target that is expected to collide with an eligible target is also excluded from the output data by determining it as being a target resulting from mispairing due to the detection of a target having many reflecting points. For a moving target showing an unlikely relative velocity, pairing with some other peak is attempted by determining the moving target as being a target resulting from mispairing due to the detection of a plurality of moving targets moving in the same direction. When there are two targets substantially equal in distance and velocity, the target located outward, as viewed from the radar-equipped vehicle, is excluded from the output data by determining it as being a ghost occurring due to reflections from a wall or like structure. After checking continuity, if the present data is not one calculated by extrapolation but the previous data is one calculated by extrapolation, filtering calculations are not performed for the calculation of the relative velocity; in other cases, the filtering calculations are performed.

摘要： There is provided a signal processing device. Data indicative of a past sensing point, and a counter value indicative of existence possibility of the past sensing point are stored in a storage. Whether the past sensing point has continuity to a recent sensing point is determined. The counter value associated with the past sensing point determined as having no continuity to the recent sensing point is decreased. The data is deleted from the storage means when the counter value becomes less than a first threshold value. The sensing point possibly detected by pairing peak signals obtained in first and second periods in a wrong manner is identified as a specific sensing point. A first value is decreased from the counter value associated with the past sensing point, and a second value different from the first value is decreased from the counter value associated with the specific sensing point.

摘要： A radar device transmits an electric wave and receives waves reflected by a plurality of objects to generate a received signal, so as to detect a plurality of up frequency peaks and a plurality of down frequency peaks from the received signal and measure characteristic values with regard to the objects at the up frequency peaks and the down frequency peaks. The radar device pairs each of the plurality of up frequency peaks with the down frequency peaks one by one and, with respect to each pair, based on the measured characteristic values, calculates a Mahalanobis distance to determine the pairs whose Mahalanobis distance is smaller than or equal to a predetermined threshold as pairing candidates. The up and down frequency peaks of the determined pairing candidates are used to calculate current data values that include at least one of a distance, relative velocity and angle of the objects.

摘要： A signal processing apparatus of a radar transceiver is provided. The radar transceiver transmits a frequency-modulated transmission signal and generates beat signals having a frequency difference between transmitted/received signals for respective receiving antennas. A distance detection section detects relative distances of objects based on frequencies of the beat signals. A phase detection section detects phases of the beat signals. A level storage section stores a first level of the beat signals that corresponds to the first object and a second level of the beat signals that corresponds to the second object when the beat signals are generated corresponding to the plurality of objects, respectively. A phase derivation section derives first and second phases in which the level of a single beat signal coincides with a sum of the first level corresponding to the first phase and the second level corresponding to the second phase on the basis of the wavelength of the beat signal and the relative distances of the plurality of objects, when the signal beat signal is generated corresponding to the plurality of objects. An azimuth angle detection section derives an azimuth angle of the first object based on the difference of the first phase and an azimuth angle of the second object based on the difference of the second phase in a pair of the antennas.
