摘要：【課題】本発明は、レーダ送信装置及びレーダ受信装置が離れた場所にあるレーダシステムにおいて、レーダ送信装置が送信タイミングをランダムにしたとしても、レーダ受信装置がレーダパルス信号をサンプリングできるようにする。【解決手段】レーダパルス信号及び符号化パルス信号は、レーダ送信装置1から同一のタイミングで送信され、それぞれ反射波及び直達波として伝搬する。よって、レーダパルス信号は、符号化パルス信号より、レーダ受信装置2へと遅れて到達する。そこで、レーダ受信装置2は、符号化パルス信号及び基準信号の相関結果に基づいて、符号化パルス信号の受信タイミングを検出し、符号化パルス信号の受信タイミングの情報を、レーダパルス信号のサンプリングトリガとして出力し、レーダパルス信号のサンプリングトリガの出力後に、レーダパルス信号のサンプリングを開始可能である。【選択図】図2
摘要翻译：要解决的问题：即使雷达发射装置在激光发射装置和雷达接收装置分别位于其上的雷达系统中随机设置发射定时，也可以使雷达接收装置对雷达脉冲信号进行采样。解决方案：雷达脉冲信号和编码脉冲信号以相同的定时从雷达发射装置1发送，分别作为反射波和直射波传播。由此，雷达脉冲信号从编码脉冲信号延迟到达雷达接收装置2。因此，雷达接收装置2基于编码脉冲信号与基准信号之间的相关结果来检测编码脉冲信号的接收定时，输出编码脉冲信号的接收定时信息作为雷达脉冲的采样触发信号，并在输出雷达脉冲信号的采样触发后，可以对雷达脉冲信号进行采样。

摘要： PROBLEM TO BE SOLVED: To provide a waveguide with slots such that a width of a slot surface is smaller than an H plane width of the waveguide, intervals of slots are at intervals where no grating lobe appears, and a plane of radiation polarization is orthogonal to a waveguide axial direction, and a waveguide slot antenna using the waveguide with the slots. SOLUTION: Plate-shaped ridges along the waveguide axial direction are stood in parallel to the H plane in the center of an E plane wall width in a rectangularly-sectioned waveguide, and slots which are long in the waveguide axial direction are provided at intervals a 1/2 as long as an in-waveguide wavelength in the waveguide axial direction so that adjacent slots are opposed each other across a ridge standing line. Consequently, the width of the slot surface is narrower than the H plane width, no grating lobe appears, and a plane of polarization is orthogonal to the waveguide axial direction. A circular polarization antenna is obtained by arranging the waveguide with the slots in parallel to a waveguide with slots whose plane of polarization is parallel to its waveguide axial direction, and a horizontal polarization nondirectional antenna is obtained by providing two waveguides with slots parallel and upright in opposite direction.

摘要： PROBLEM TO BE SOLVED: To suppress the occurrence of a vertically polarized wave component while suppressing the mass and manufacturing cost of an antenna. SOLUTION: In the slot antenna 100, the distance along the footprint portion between the parallel portion of a supporting portion 26 and one side of the H-face portion of a waveguide 12 opposing the parallel portion is adjusted such that the amplitude of the vertically polarized wave component of a first radio wave radiated from a slot becomes equal to the total of amplitude of a second radio wave radiated from the footprint portion. The distance along the H-face portion between the footprint portion of the supporting portion 26 and the E-face where the slot is provided is adjusted such that the phases of the second radio waves are equalized while having such a relation as the phases of the vertically polarized wave component of the first radio wave and the second radio wave are inverted. The supporting portion 26 supports the waveguide 12 such that no air gap exist between. A conductive substance may be inserted between the supporting portion 26 and the waveguide 12.

摘要： PROBLEM TO BE SOLVED: To provide a method for simply determining delay time of an antenna for calculating the electrical length of an antenna.
SOLUTION: Two models of patch antennas 10 and 20 are prepared and disposed opposite to each other. Transmission characteristics S21 between input and output ports 14 and 24 of the two antennas 10 and 20 are found by means of electromagnetic field simulation. Delay time between the input and output ports 14 and 24 is found from the transmission characteristics S21. The delay time t2 of the antenna is found by multiplying by 1/2 a value obtained by subtracting propagation delay time t0 in free space with the two antenna models opposite standing therein from the obtained delay time t1.
