Abstract: In a vehicle control apparatus, a rear side detecting unit, mounted to an own vehicle, detects another vehicle that is present in a first area behind and to a side of the own vehicle. A time acquiring unit, mounted to the own vehicle, acquires a first time that is an estimated time at which a front approaching vehicle will arrive at the first area. The front approaching vehicle is another vehicle that is relatively nearing the own vehicle from ahead of the own vehicle. A sensitivity setting unit, mounted to the own vehicle, sets a detection sensitivity of the rear side detecting unit to the other vehicle in at least a part of the first area in such a manner that the detection sensitivity during a predetermined period set based on the first time is higher than the detection sensitivity during a remaining period other than the predetermined period.

Abstract: An antenna device includes: antennas; magnetic oscillation element units converting electrical energy to high-frequency power; and a modulator outputting electrical energy input from outside to at least two magnetic oscillation element units, with a time difference to differentiate phases of high-frequency power converted from electrical energy by at least two magnetic oscillation element units. The magnetic oscillation element units respectively include a pair of electrodes, and further include, between the pair of electrodes, a PIN layer, a free layer, and an intermediate layer. A resistance value of an element configured by the PIN, free and intermediate layers changes according to the angle between the magnetization direction of the PIN layer and the magnetization direction of the free layer. The antennas transmit electromagnetic waves to open space outside the magnetic oscillation element units with the supply of high-frequency power.

Abstract: In a dual-frequency CW radar apparatus, first/second beat signals that include reflection components of radar waves conforming to transmission signals of first/second frequencies are generated for each antenna element and the generated signals are Fourier transformed. A power spectrum average of the beat signals is used as a basis for the detection of a peak frequency fp corresponding to the frequency of the reflection components. A second eigenvalue ?2 of a correlation matrix: Ry=(½)·[y1,y2][y1,y2]H is calculated, the matrix being based on first received vector y1/second received vector y2 having elements that are Fourier transformed values of the peak frequency fp. Based on the magnitude of the eigenvalue ?2, whether or not the reflection components corresponding to the peak frequency fp are synthetic components of the reflected waves from a plurality of targets is decided.

Abstract: A sampled beat signal RD is split into a plurality of short-time data SD in the time direction, for each of antenna elements. Interference component frequency of an interference wave is detected from a frequency spectrum of the short-time data SD. A digital beam forming process is performed for the interference component frequency of the interference wave to extract a peak of the electrical power of an azimuth direction and estimate an absolute value of an incoming direction of interference components. Based on the absolute value of the incoming direction of the estimated interference components, a filter for suppressing the interference components is operated to suppress the interference components.

Abstract: A FMCW-type radar device generates snapshot data from a beat signal that represents a received condition of the radar device every modulation period. Auto-correlation matrices generated by the snapshot data every modulation period are averaged every set of plural periods. The radar device calculates the target azimuth of a target object such as a preceding vehicle based on the averaged auto-correlation matrix based on MUSIC (MUltiple SIgnal Classification) method. This averaging is performed by weighting average based on an amount of mixed noise (or an interference amount) contained in the snapshot data in each modulation period. A weighting coefficient to be applied to the auto-correlation matrix in each modulation period is set to a value corresponding to the amount of mixed noise, namely, the interference amount of this modulation period. The weighting coefficient becomes large when the interference amount is small, and on the other hand, becomes small when it is large.
