摘要： PROBLEM TO BE SOLVED: To surely discriminate a plurality of targets by a radar device.
SOLUTION: Transmission signals having three or more kinds of frequencies are outputted from an oscillator 10, and transmission waves are radiated from a transmitting antenna 14 toward a target 100. Reflected waves are received by a receiving antenna 16, and the transmission signal is mixed with a receiving signal by a mixer to generate a beat signal. A signal processing device 24 detects a Doppler frequency signal from the beat signal by FFT and detects a distance to the target 100 by Fourier analysis, by using a complex signal component of the Doppler frequency signal in each channel as a progression. The maximum detection distance is increased by differentiating a frequency difference between the three or more kinds of transmission signals.

摘要： PROBLEM TO BE SOLVED: To provide a cover for radar devices of a vehicle equipped with high design property by three-dimensional shape, inhibiting directional disturbance of radars. SOLUTION: The cover 1 for radar devices of the vehicle is of three-dimensional corrugated shape making dielectric plate to be flexed to prepare unevenness. The thickness of a first part 6 which is a part perpendicular to wave front of the electromagnetic wave transmitted and received by millimeter wave radar device 2 of dielectric plate is thinner than the thickness of a second part 7 of the other part. Thereby, because decreasing amount of electromagnetic wave permeating the first part 6, influence of phase shift is relatively reduced to inhibit directional disturbance of radars.

摘要： PROBLEM TO BE SOLVED: To appropriately detect obstacles only by a method using wave motion in an obstacle detector. SOLUTION: The obstacle detector 20 mounted on a vehicle has a basic configuration of a conventional vehicle-mounted FM-CW radar which has been being used for obstacle detection and determines the presence or absence of objects by a primary determination module 52 of a control section 50. When the presence of an obstacle is determined, the reception power of received waves is acquired at a predetermined control period and taken as reception power time-series data and compared with a threshold range pattern preset on the basis of the phase interference of wave motion dependent on the height of the object from a road to determine whether the object is an object on the road or not at a secondary determination module 54.
