摘要： A radio environment analysis apparatus includes a receiver and signal processor. The receiver receives a signal modulated by phase shift keying (PSK) using a pseudo noise (PN) code sequence by an array antenna at a plurality of fixed points on the plane, converts the received signals into intermediate frequencies or demodulated signals, and outputs them. The signal processor processes a signal output from the receiver to analyze the arrival angle, delay time, and relative power of the signal incoming to the receiver. The signal processor has a plurality of normalization units, first estimation unit, arithmetic unit, and second estimation unit. The normalization units individually normalize signals from the receiver and output them as a normalized signal group. The first estimation unit calculates a covariance matrix, and estimates the arrival angle of each incoming signal. The arithmetic unit calculates a weight of the array antenna for suppressing incoming signals except for an incoming signal having the estimated arrival angle, and calculates the product of the weight of the array antenna and the normalized signal group. The second estimation unit calculates a covariance matrix and estimates the delay time and relative power.
摘要翻译：无线环境分析装置包括接收机和信号处理器。接收机通过阵列天线在平面上的多个固定点处使用伪噪声（PN）码序列接收由相移键控（PSK）调制的信号，将接收到的信号转换成中频或解调信号，并将它们输出。信号处理器处理从接收器输出的信号，以分析入射到接收机的信号的到达角度，延迟时间和相对功率。信号处理器具有多个归一化单元，第一估计单元，运算单元和第二估计单元。归一化单元将来自接收器的信号归一化，并将其作为归一化信号组输出。第一估计单元计算协方差矩阵，并估计每个输入信号的到达角度。算术单元计算用于抑制除了具有估计到达角度的输入信号之外的输入信号的阵列天线的权重，并且计算阵列天线和归一化信号组的权重的乘积。第二估计单元计算协方差矩阵并估计延迟时间和相对功率。

摘要： A plurality of antennas receives radio wave transmitted from a vehicle which comes in a toll collection area. Each antenna has at least three antenna elements, and the antennas are disposed in the horizontal direction and vertical direction. The signal analyzer analyzes the ID signal included in the received radio wave to identify the vehicle. The direction detector measures the direction of arrival (DOA) of radio wave received by two antennas selected by the antenna selector by way of two-dimensional interferometry principle in terms of the directional angle and depression angle. The location detector calculates the location of the vehicle in the horizontal direction and the height in the vertical direction of the vehicle as a location information based on the DOA of the radio wave measured by the direction detector. The vehicle tracking unit generates the locus data of the vehicle based on the location information calculated by the location detector and the information for identifying the vehicle analyzed by the signal analyzer. On the other hand, the video camera takes a picture of the vehicle which comes in the toll collection area to obtain the picture data. The data correlation unit judges whether the vehicle is a violator vehicle by correlating the picture data and locus data. The controller registers the locus data and picture data of the vehicle if the vehicle is a violator vehicle. On the other hand, the controller collects a prescribed toll from the vehicle if the vehicle is not a violator vehicle.
摘要翻译：多个天线接收从进入收费区域的车辆发送的无线电波。每个天线具有至少三个天线元件，天线设置在水平方向和垂直方向上。信号分析仪分析包括在接收到的无线电波中的ID信号以识别车辆。方向检测器通过二维干涉测量原理在方位角和俯角方面测量由天线选择器选择的两个天线接收的无线电波的到达方向（DOA）。位置检测器基于由方向检测器测量的无线电波的DOA，计算车辆在水平方向上的位置和车辆垂直方向上的高度作为位置信息。车辆跟踪单元基于由位置检测器计算的位置信息和用于识别由信号分析器分析的车辆的信息来生成车辆的轨迹数据。另一方面，摄像机拍摄来自收费区域的车辆的图像，以获得图像数据。数据相关单元通过使图像数据和轨迹数据相关来判断车辆是否是违规车辆。如果车辆是违规车辆，则控制器登记车辆的轨迹数据和图像数据。另一方面，如果车辆不是违规车辆，则控制器从车辆收取规定的费用。
