Abstract: An object of the present invention is to provide an impact absorbing member capable of reinforcing a desired reinforcement object portion. The impact absorbing member includes a long impact absorbing body which absorbs energy at the time of a collision by being deformed itself and a mounting member which is disposed at a reinforcement object portion of the impact absorbing body so that it is deformed along deformation of the reinforcement object portion at the time of the collision and mounted to a mounting object member. When the reinforcement object portion is deformed at the time of the collision, the mounting member is deformed along deformation of the reinforcement object portion. Due to that deformation, the mounting member can reinforce the reinforcement object portion.

Abstract: When an excitation signal is generated from an exciter due to an activation signal generated from a radar control device and is distributed to supply to each antenna sub-module, a combination reception signal is transmitted to a receiver from each antenna sub-module. The receiver takes in the combination reception signal obtained by each sub-module in response to an instruction from the radar control device, a frequency converter converts the combination reception signal into a prescribed frequency band, and a distributed aperture combination circuit performs a beam combination in accordance with a distributed aperture combination algorithm. In this way, a radar apparatus, which is equivalent to an active phased array radar of a large aperture and with high performance, is achieved.

Abstract: In a transceiver module, a micro wave analog signal interface is provided between the transceiver module and an antenna element, and all the signal interfaces except a power supply are digital signal interfaces, and the interfaces are configured as one chip on a semiconductor. An internal reference signal generates a local signal serving as a reference by multiplying a high frequency digital clock signal supplied from the outside, and simultaneously generates a reference signal capable of synchronous operation by a lower frequency digital clock signal supplied from the outside, in the clock generator. The frequency of the generated reference local signal can be varied by controlling the inner multiplication number or the frequency of the higher frequency digital clock signal supplied from the outside. In addition, both transmission and reception can be executed with an arbitrary frequency by varying the frequency of the transmission waveform generator.

Abstract: A received data storage situation is monitored, and a covariance matrix Ri of the i-th range cell is calculated to be temporarily stored. Covariance matrices Ri of the number of training samples are called until the i becomes T from 1, covariance matrices Ri are averaged by adding, and averaged covariance matrix data R[1]rr is temporarily stored. Averaged covariance matrix data R[i?1]rr is called until the i becomes L from 2, Ri and Ri?4 are added to the data R[i?1]rr, Ri+3, and Ri?1 are subtracted from the data R[i?1]rr, the resulting data R[1]rr is temporarily stored, and a series of processing is terminated.

Abstract: A weight calculation method begins by storing a target reflection signal of a radar pulse received via an antenna in cells corresponding to positions along with a reception timing for a plurality of processing range cells having lengths equivalent to prescribed ranges on a time axis. The method continues by calculating weights by stage for the phase and amplitude of the target reflection signal to form a reception composite beam so that arrival directions of spurious elements become zero to an arrival direction of the target reflection signal by using values stored in the plurality of processing cells. The calculating of the weights monitors changes of specific variables indicating correlation values among stages in the plurality of processing stages to stop a shift to the next processing stage at the time when the variables exceed a reference value.

Abstract: An object of the present invention is to provide an impact absorbing member capable of reducing a load at a load reducing object portion easily and a manufacturing method thereof. The impact absorbing member includes a long impact absorbing body in which the sectional shape in the direction of a short side thereof is substantially identical throughout the entire length in the length direction and at least one load reducing hole arranged in the load reducing object portion of the impact absorbing body. Because the load reducing hole is disposed, the load on the load reducing object portion can be reduced. Further, the load on the load reducing object portion can be reduced by a relatively simple work of arranging the load reducing hole.
