Description

Technical Field

[0001] This utility model relates to the field of thermal radiation technology, and in particular to a portable thermal imaging target strip and frame target. Background Technology

[0002] During nighttime live-fire training, traditional aiming techniques often result in unclear target visibility. However, with the advent of infrared aiming technology in recent years, thermal targets have effectively solved this problem. The target surface is designed as a heat source, creating a thermal image that differs from the surrounding environment. The infrared aiming device on the launcher is then used to determine the specific location of the live-fire target.

[0003] Currently, live-fire training in the military uses surface targets, typically set up for nighttime training using methods such as electric blankets, charcoal-heated target cloths, or suspended burning charcoal grills. These types of targets are relatively large, making them easy to hit when projectiles are densely packed, and they are unusable after damage, resulting in low economic efficiency and applicability. Furthermore, some targets have low radiation temperatures, making it difficult to distinguish the target from the training environment and reducing training effectiveness. In addition, military training is generally conducted in the field, so target design should be portable, easy to install, and adaptable to field environments. Therefore, we provide a portable thermal imaging target strip and frame target suitable for various environments such as darkness, rain, snow, fog, and dust, offering advantages such as portability, sustainability, low consumption, and ease of installation.

[0034] In this embodiment, the carbon fiber filament has the following specifications: 24K, tensile strength of 4900MPa, electrical resistance of 18Ω / m, elongation of 2.1%, and density of 1.80g / cm3.

Generally, the thickness is (2-5) cm, the width is (4-10) cm, and the length is (0.8-2) m. The outer side of the bottom layer 4 of the thermal imaging target strip can be provided with a hanging strap 7 as needed.

The multiple thermal imaging target strips are connected end to end by the electrode 5, and the multiple thermal imaging target strips can be connected in parallel to the circuit. After the power supply 6 is turned on, a resistance heating effect is generated simultaneously to form a frame-shaped thermal imaging target.

[0050] In this embodiment of the present invention, the power supply 6 is preferably a low-voltage DC power supply with an output of (45~75)V. When used in the field, there is no need to find a power supply device, which effectively improves the applicability of the thermal imaging target to the field environment. The resistance of the heating zone 1 can be designed according to the length of the target strip, generally (30~80)Ω, preferably 40Ω with a target strip length of 1m. The current passing through the carbon fiber is preferably (1.2~1.8)A, and the brightness temperature of the thermal imaging target strip is preferably (100~200)℃. The higher the output voltage of the power supply, the higher the radiation brightness temperature of the thermal imaging target strip, and the easier it is for the target to be identified.

[0051] This invention allows for multi-level adjustment of the radiation brightness of the thermal imaging target, effectively improving its energy efficiency and environmental adaptability. The unique internal circuit and electrode design of the thermal imaging target strip enables the simultaneous and rapid parallel connection of multiple target strips into the circuit, facilitating installation. The frame-shaped target design results in a low damage rate during live-fire shooting and a high rate of sustainable use. The target frame size is adjustable, allowing the target size to be changed at any time according to the needs of troop training.
