Abstract: A radar apparatus forming a series-feed array-antenna includes an array antenna having transmission/reception antennas, and each antenna includes a plurality of antenna elements arrayed with feed-lines to be series-connected each other. A calibration line is disposed between the transmission antenna and the reception antenna via a switch which connects or disconnects the calibration line. The signal having a phase shift is transmitted via the calibration line when the switch connects the calibration line and an amount of phase shift from the signal transmitted via the calibration line is calculated based on a reference phase at the transmission antenna thereby calibrating the phase shift.

Abstract: A radar system includes an arithmetic processing unit, which sends a warning command to a warning device when a local minimum point of the intensity of the reflected wave from a target within a predetermined detection range is detected. By determining whether it is necessary to send a warning command based on whether there is a local minimum point of the intensity within the detection range, it is made possible to determine whether it is necessary to send a warning command more quickly as compared to the conventional system.

Abstract: A radar system includes radars and a controller. The controller controls waveform patterns of the radars. As a signal processing unit of each of the radars receives an instruction from the controller, the signal processing unit selects a frequency modulation pattern of a VCO between an FM-CW mode and a CW mode stored in a waveform memory to perform mode switching, and then outputs a radio wave from a transmission antenna. Then, the controller instructs each signal processing unit for a frequency modulation pattern of each radar or an output timing of each pattern so that a time, at which continuous wave signals output from the radars have the same frequency, is not continuous.

Abstract: In an integrated optical unit of the present invention, a photo detector (12) and a holding member (17) that sustains a semiconductor laser (11) are provided on a polarizing beam splitter (14). This makes it possible to reduce a deviation from a designed value due to tolerance, and adjust a relative positional relationship between the semiconductor laser (11) and the photo detector (12). Therefore, returned light from an optical disk (4) is accurately adjusted with respect to a division line of a photo-detecting device (13). As a result, stable servo-control is realized, and an information signal with fine quality is obtained.

Abstract: A feed probe (1), a semicylindrical sub-reflector (2) forming a primary radiator together with the feed probe (1), and a main reflector (3) arranged such that mirror surfaces of said main reflector (3) and the sub-reflector face across the feed probe (1) are all disposed on a ground plate (a recfector face) (4). The main reflector (3) has a predetermined focal point or focal line on which the feed probe (1) is located, and is mounted on the ground plate (4) at a predetermined installation angle θ. A converter (500) for converting linearly and circularly polarized waves is provided on the mirror surface of the main reflector (3). The converter (500) is composed of a plurality of grooves (510) and ridges (512) formed between the grooves, so that a wave component orthogonal to the grooves is reflected at the bottom of the grooves while a wave component parallel to the grooves is reflected on the ridge surface, thereby causing a phase difference according to the height H of the grooves when a radio wave is reflected on the main reflector to thereby perform linear to circular polarization conversion.
