In this case, the length of the towing line 7 by which the target machine 11 tow the optical measurement tow pod 10 is long enough to prevent the optical measurement tow pot 10 from being shaken by the wake of the target machine 11, and By setting the length to be short enough to capture a detailed image of the target device 11, the measuring camera 1 can always capture the target device 11 within the imaging range 1a. The controller 4 controls the imaging of the state of the association between the target aircraft 11 and the guided flying object 13 by the measurement camera 1.

In FIG. 1, the tow release device 2 is installed at a position where the tow line 7 is connected to the tow pod 10 for optical measurement so as not to hinder the photographing by the measurement camera 1 arranged in front. It is installed at the upper center of the towing pod 10 for optical measurement. The traction release device 2 includes a controller 4
, The towing line 7 is separated from the tow pod 10 for optical measurement, and the restraint from the target machine 11 is released.

The parachute 3 is built in the tail cone 8 at the rear end of the towing pod 10 for optical measurement, and the suspension arm 9
Connected to. When the tail cone 8 receives an umbrella opening command from the controller 4, the tail cone 8 is separated from the main body of the towing pod 10 for optical measurement, and the parachute 3 incorporated in the tail cone 8 opens and the suspension connected to the parachute 3. An optical measurement towing pod 10 is suspended via the arm 9. The parachute 3 is a towing pod 10 for optical measurement.
, The parachute 3 can be securely opened.

FIG. 3 is a view showing a state in which the towing pod 10 for optical measurement is suspended by the parachute 3. As shown in FIG. 3, the suspension arm 9 is
Is set at the position of the center of gravity of the main body of the optical measurement towing pod 10, so that the optical measurement towing pod 10 descends while maintaining a horizontal posture, thereby landing the optical measurement towing pod 10. Minimize the impact of time. Minimizing the impact of the optical measurement towing pod 10 at the time of landing can minimize damage to the optical measurement towing pod 10, thereby enabling the optical measurement towing pod 10 to be reused. Become.

The controller 4 is installed inside the central portion of the tow pod 10 for optical measurement, and is connected to at least the measurement camera 1, the traction release device 2, the receiving antenna 5, and the tail cone 8. The controller 4 receives a wireless control command from a terrestrial transmitting station (not shown) via the receiving antenna 5, and controls the measurement camera 1, the traction release device 2, and the umbrella opening of the parachute 3 folded in the tail cone 8. . The receiving antenna 5 is installed below the optical measurement towing pod in order to reliably receive a wireless control command from a ground transmitting station (not shown).

Here, a control processing procedure by the controller 4 will be described with reference to a flowchart shown in FIG. 4, first, the controller 4 determines whether or not an imaging start command has been received from a ground transmitting station (not shown) via the receiving antenna 5 (step S1). If the imaging start command has not been received (step S1, NO), this determination process is repeated, and if the imaging start command has been received (step S1, YES), the imaging by the measuring camera 1 is started (step S1, YES). Step S2). Thereafter, the controller 4 determines whether a pod collection command has been received (step S3). If the pod collection command has not been received (step S3, NO), the process proceeds to step S2 and the imaging by the measurement camera 1 is continued, and if the pod collection command has been received (step S3, YES), the measurement camera 1 Is stopped (step S4).

After that, the controller 4 sends a separation command to the towing release device 2 to cause the towing cable 7 to be disconnected (step S5), and further sends an umbrella opening command to the tail cone 8 to send the tail cone. When the parachute 3 is separated from the tow pod 10 for optical measurement, the parachute 3 is opened (step S6), and the process is terminated.

Thereafter, as shown in FIG. 3, the optical measurement towing pod 10 softly lands on the ground surface or the sea surface while maintaining the horizontal state. Soft landing optical measurement pod 10
Is reused by repairing damaged parts.

In the embodiment described above, the towing line 7
And the towing pod 10 for optical measurement are separated, and the towing line 7 is connected to the target machine 11 side, but not limited to this.
The target machine 11 and the towing line 7 are separated, and the separated towing line 7 is separated.
May be connected to the tow pod for optical measurement.

According to the tow pod for optical measurement according to the present invention (claim 3), the parachute is connected to the suspension arm supported by the position of the center of gravity of the tow pod for optical measurement, and Since the tow pod for optical measurement is dropped while maintaining the tow pod in a horizontal state, the shock when the tow pod for optical measurement falls on the ground surface or the sea surface is relieved, and the tow pod for optical measurement is reduced. This has the effect of reducing damage to the surface.

According to the tow pod for optical measurement according to the present invention (claim 4), the receiving means has a receiving antenna, and the receiving antenna is installed below the tow pod for optical measurement. Since a predetermined wireless control command transmitted from the ground side is received, it is possible to reliably receive the predetermined wireless control command from the ground side.

According to the tow pod for optical measurement according to the present invention (claim 5), the length of the tow line is short enough that the imaging means can image the meeting situation with a sufficient resolution, and Since the length is set to be long enough not to be shaken by the wake of the target machine, it is possible to capture an image having a sufficient resolution and to obtain a stable image. .

According to the tow pod for optical measurement according to the present invention (claim 6), the parachute is stored and arranged at the rear of the tow pod for optical measurement in the traveling direction.
Since the umbrella opening of the parachute is reliably performed, the soft landing of the tow pod for optical measurement can be reliably performed, and the effect of reliably reusing the tow pod for optical measurement can be obtained.
