FIG. 2 is a diagram showing an example of display contents of the display device of the present invention. In the drawing, reference numeral 15 denotes an aiming reticle, and reference numeral 11 denotes aiming deviation information.

Next, the operation will be described with reference to FIGS. Since the shooter needs to hold the small arms 1 and both hands are blocked, the aiming operation is performed by the head mounted display or the display 14 which is formed integrally with the small arms 1 or the image pickup device 2. The imager 2 has an aiming reticle in the center of the field of view and is fixed to the small arms 1. Further, the aiming goniometer 3 is attached to the small arms 1 or the image pickup device 2, and is adjusted so that the angle measuring axis is parallel to the aiming reticle. Aiming goniometer 3
Consists of, for example, an inclinometer and an azimuth sensor, the inclinometer measures an elevation angle based on a horizontal plane, and the azimuth sensor measures an azimuth angle based on a magnetic north reference. Such a goniometer has a size of one A6 size substrate, and realizes a relative angle of about 0.1 degree, and can measure the direction with an error within 1 m even at a distance of 500 m. The receiver 8 receives the target position information 9 transmitted from the target position information transmitting means 16. Target position information 9
The self-position information 7 measured by the self-position measuring means 6 includes the latitude, longitude, and altitude information of the target and the self-position, respectively. The deviation angle calculating means 10 calculates the target azimuth based on the self-position, the distance to the target, and In addition to calculating the elevation difference, the azimuth angle of the target direction with respect to the aiming reticle 15 and the elevation angle deviation are calculated from the aiming azimuth angle of the small arms 1 and the aiming direction information 5 including the elevation angle information obtained by the aiming goniometer 3.
