摘要： An apparatus for detecting a direction of a target is provided. The apparatus transmits and receives radio waves through a plurality of transmission/reception channels causing a phase difference in signals to be received through the transmission/reception channels and calculates the direction based on the phase difference. The apparatus comprises a direction calculating device, range determining device, and direction correcting device. The direction calculating device calculates the direction of the target based on the phase difference in the received signals on the assumption that the phase difference is within a range of −π to +π [rad]. The range determining device determines that the target exists in any of azimuthal angle ranges each corresponding to ranges defined by (2m−1)π to (2m+1)π [rad] (m is an integer). The direction correcting device corrects the direction according to a range-determined result.

摘要： A radar apparatus is provided which is capable of discriminating between azimuth angles of two or more targets moving side by side close to each other. The radar apparatus provides antenna beams which partially overlap with each other to define a plurality of monopulse areas and processes input signals produced in each of the monopulse areas to obtain angular direction data. The radar apparatus determines a time-sequential variation in angular direction data in each of the monopulse areas and determines the angular direction data whose variation is within a preselected allowable range as being effective in determining the angular direction of each target correctly.

摘要： A vehicle radar system extracts peak frequencies fbu and fbd of respective beat signals B1 to B9 representing the frequency difference between a transmission signal fs and a plurality of received signals fr1 to fr9. The phase difference of respective beat signals B1 to B9 at the peak frequencies fbu and fbd is converted into a frequency signal. In the case of reflection from a close range road surface or raindrops, the phase difference of each beat signal is irregular. The peak frequency intensity of a converted frequency signal is small. This system compares the peak frequency intensity of the converted frequency signal with predetermined criterion intensity. Then, the system identifies an objective with a close range road surface or raindrops when the peak frequency intensity of the converted frequency signal is not larger than the predetermined criterion intensity.

摘要： A radar system mounted in a reference vehicle can detect a distance and orientation of a preceding vehicle to thereby compute a relative position of a width center of the preceding vehicle. A curving radius of the reference vehicle is then detected for computing a relative rotation angle between a direction from the reference vehicle and a longitudinal direction of the preceding vehicle. Relationship between a relative rotation angle and a lateral bias of the relative position of the width center is previously prepared in a map. The computed relative rotation angle is applied on the map, so that the corresponding lateral bias is obtained to correct the computed relative position of the width center of the preceding vehicle. Thus, the width center of the preceding vehicle moving in an adjacent lane can be accurately estimated.

摘要： The present position of a previously recognized stationary object group (SOp) is estimated based on past position data and the movement of the traveling vehicle during a past time (&Dgr;T). A clearance (Mwr, Mwl) between a traveling vehicle (Mx) and an adjacent stationary object group (Mxr, Mxl) is obtained based on the estimated position data. A clearance (Twr, Twl) between a preceding vehicle (Tx) and an adjacent stationary object group (Txr, Txl) is obtained based on the estimated position data and the position data of the preceding vehicle. A same lane judgement is performed to judge whether the traveling vehicle (VM) and the preceding vehicle (VT) are traveling on a same traffic lane based on at least one of the detected clearances (Mwr, Mwl, Twr, Twl).

摘要： Provided is a radar apparatus capable of continuously and stably making a detection of a target even if a reflected wave from a target already detected falls into obscurity due to the presence of low-frequency noises or reflected waves from other targets. An estimated value of information on a target to be obtained when the target is detected in the present cycle are acquired from the target detected in a previous cycle. When a peak compatible with the estimated value is detected in only one of a frequency-rising section and a frequency falling section of a radar wave, if the frequency of the non-detected peak pertains a low-frequency noise domain or if a side-by-side travel flag is set with respect to the target detected in the previous cycle, the non-detected peak is considered as buried by low-frequency noises or peaks of other targets, and a peak pair corresponding to the detected target is extrapolated.
