    • A radar device separates directions of a plurality of targets, obtained from combinations of antenna beams, with a high accuracy. The radar device includes: a direction calculating unit for calculating a primary direction, which is the direction of a target, from a combination of characterizing quantities calculated by a signal detector from the reception waves of at least two beams that partially overlap, among the beams radiated in the plurality of directions; and a direction integrating unit for, when a plurality of primary directions calculated by the direction calculating unit is present, calculating an integrated direction, which is the true target direction, from an area in which distribution of the plurality of primary directions is a predetermined density or greater, based on the primary directions belonging to the area.

    • For the purpose of depositing deviation-free dichroic coatings of high plane rectitude, there is disclosed a method starting with preparation of glass assembly units each composed of first and second glass members of different lengths. A first dichroic coating 10A is deposited on a lateral side of one glass member, and the other glass member is joined on the first dichroic coating 10A on the one glass member to obtain a glass assembly unit 5. A lateral side of the glass assembly unit 5 is ground to one and same plane at an angle of 90 degrees, and then two edge lines on the opposite side are ground at an angle of 45 degrees to obtain a prism member. A second dichroic coating is deposited on the prism member, and joined with another prism member without a second dichroic coating to obtain a parental cross prism material to be cut into cubes for use as cross prisms.
    • 为了沉积具有高平面直角度的无偏差二向色性涂层,公开了从制备玻璃组件单元开始的方法,每个玻璃组件单元由不同长度的第一和第二玻璃构件组成。 第一分色涂层10A沉积在一个玻璃构件的侧面上,另一个玻璃构件在一个玻璃构件上的第一分色涂层10A上接合,以获得玻璃组合单元5.玻璃的侧面 组装单元5以90度的角度被研磨到同一平面,然后在相对侧上的两条边缘线以45度的角度被研磨以获得棱镜构件。 第二分色涂层沉积在棱镜构件上,并且与另一个棱镜构件接合而不用第二分色涂层,以获得待切割成立方体的母体十字棱镜材料,以用作十字棱镜。
