摘要: A single antenna is used so that time-division transmission and reception is carried out in a radar apparatus for obtaining a distance and a relative speed with respect to a target object based on a beat signal obtained by transmitting a frequency modulated signal and mixing a received signal reflected by said target object with the frequency modulated signal that is transmitted.

摘要: To reduce the processing load such as channel assignment and an authentication process in a plurality of radio base stations and communication terminals, and quickly and efficiently assign channels to the communication channels. The channel assigning method by a radio base station group, includes determining assignment of a communication channel between a communication terminal entering a radio area of the radio station group and all radio base stations within the radio station group by a base station in the radio base station group. Channel assigning information common to the radio base station group is updated as to the determined communication channel and a communication channel is assigned to the communication terminal with reference to the channel assigning information by each radio base station in the radio base station group other than the radio base station.

摘要: An array antenna radar apparatus has a single front end shared by a plurality of antennas, a first switch for cyclically connecting the antennas to the front end at a prescribed switching frequency, and a second switch for cyclically connecting the output of the front end to frequency converters corresponding to the antennas. The frequency converters frequency-convert intermediate-frequency signals of the respective antennas output by the front end to baseband signals at the switching frequency. Phase shifters and amplitude adjusting units apply a phase shift or amplitude adjustment to the outputs of the frequency converters and combine the resulting signals, thereby making it possible to detect a target in a desired direction.
