    摘要： A navigation system which can enhance the position determining accuracy of a mobile object without employing any high precision measuring instrument. The navigation system comprises a GPS range measuring device (101 in Fig. 1), an angular velocity measuring device (102), a velocity measuring device (103) and an azimuth measuring device (104), which measure the motion of the mobile object; a GPS range error estimating device (105), an angular velocity error estimating device (106), a velocity, error estimating device (107) and an azimuth error estimating device (108), which estimate errors involved in the respectively corresponding measuring devices; and a position calculating device (109) which calculates the position of the mobile object from the outputs of the error estimating devices. The error estimating devices are implemented by Kalman filters and averaging processes. The factors of the errors of the individual measuring devices are assumed, and the outputs thereof are corrected, so that the position of the mobile object can always be determined at a high accuracy without employing any high precision sensor.

    摘要： The invention relates to a millimeter wave radar (1) that is used for the purpose of automatic operation or collision prevention of a vehicle, it is intended to solve the Problem that a side lobe (8) of a transmitted electromagnetic wave is reflected by surrounding bodies and the reflected wave is received, with the result that unnecessary bodies may also be detected. A layer higher in dielectric loss than a radome (2) or a magnetic loss layer (9) and a conductor layer (10) in a mesh form are embedded in a part of the inside surface of the radome (2), whereby it is possible to provide a millimeter wave radar (1) which is light in weight, excellent in weathering performance, inexpensive, and excellent in detection performance.
