    摘要： An apparatus for classifying a true target includes a signal processor configured to perform range processing on an input signal in a fast time direction and Doppler processing on the input signal in a slow time direction to output an output signal in a range-Doppler domain, a detector configured to output a hit by detecting a target signal within an output signal on which the range processing and the Doppler processing have been performed in the signal processor, a total energy calculator configured to calculate a total energy value of the input signal of the signal processor in the slow time direction or a total energy value which is a sum of power spectra of the output signal of the signal processor in the Doppler direction, a Doppler ratio value calculator configured to calculate a Doppler ratio value of the hit detected in the range-Doppler domain using the total energy value, and a false target remover configured to compare the Doppler ratio value with a threshold value and determine a hit having the Doppler ratio value smaller than the threshold value as a false target.

    摘要： Disclosed are a soft recoil system (200) and a cannon (100) having the same. The soft recoil system (200) includes: a cannon barrel returning device (210) mounted to a recoil device (160) for absorbing a recoil force occurring when ammunition is fired, and configured to backward press a breech ring (150) coupled to a rear end of the cannon barrel (120), such that the cannon barrel (120) is fixed to a preset position; a cannon barrel fixing device (220)installed at the recoil device (160), and configured to fix the cannon barrel (120) when the cannon barrel (120) returns to the fixed position; and a forward momentum generator (230) connected to the recoil device (160) and the breech ring (150), respectively, configured to forward move the cannon barrel by applying a force to the breech ring (150), such that the ammunition is fired while the cannon barrel (120) forward moves, and configured to reduce a recoil force by partially attenuating recoil momentum resulting from the firing of the ammunition, by forward momentum.

    摘要： A rifling angle calculating method according to the present invention expands a rifling angle by combining a Fourier function and a polynomial function to take only the advantages of the two functions, and thus boundary conditions at the start and end points of the rifling angle may be faithfully satisfied, and an optimum rifling angle for minimizing the maximum rifling force may be calculated.

    摘要： Disclosed are a cavitation device (140) and an underwater moving body (100)having the same. The underwater moving body (100) includes a body(110); and a cavitation device (140) for generating a cavity which encloses an outer circumferential surface of the body (110), wherein the cavitation device (140) includes: a plurality of flap-up/down members (141) rotatably connected to the body (110), disposed to cover the outer circumferential surface, and disposed in a circumferential direction and a lengthwise direction of the body in a matrix form; and a pressing module(143) for flapping up the flap-up/down members (141) such that the cavity is generated, as the flap-up/down members (141) are being rotated and inclined from the outer circumferential surface. Furthermore, a ventilation module (144) for forming a ventilated cavity may be coupled to the cavitation device (140).

    摘要： The present disclosure relates to an airburst simulation system and method. The airburst simulation system includes a laser emitting unit to emit laser beam to an airburst aiming position, preset above a target hidden behind an obstacle, such that a warhead is airbursted to shoot the target, a laser detecting unit mounted onto the target to detect an arrival of the laser beam above the target, and a determining unit to measure a distance between the airburst aiming position and an arrival position of the laser detected by the laser detecting unit, and determine whether or not the target has been shot based on the distance. This allows for a simulated engagement using an airburst apparatus, with no harm to human bodies by virtue of the use of laser.

    摘要： Disclosed are a steering control device of an autonomous vehicle, an autonomous vehicle having the same, and a steering control method of an autonomous vehicle. The steering control method comprises receiving a position of an autonomous vehicle, and a first heading angle of the autonomous vehicle with respect to the north; calculating a second heading angle of the autonomous vehicle toward a tracking waypoint based on the position of the autonomous vehicle, and computing a rotation radius of the autonomous vehicle with respect to the tracking waypoint; calculating a yaw rate based on a speed of the autonomous vehicle and the computed rotation radius, and generating a steering command corresponding to the calculated yaw rate; and compensating for the steering command based on the first and second heading angles.
