A combustion gas piston type movable guiding tube netting device includes a capture net (), a traction head (), a guiding tube (), an igniter (), a main gunpowder (), a combustion gas generator () and a piston (). The piston and the main gunpowder are placed in the combustion gas generator. The top of the piston contacts a triangular lug on the base of the guiding tube. The traction head is placed in the guiding tube, and another end of the traction head is tied on one corner of the capture net. When operating, the main gunpowder is ignited by the igniter, the resulting combustion gas pushes the piston to move, the piston pushes the guiding tube to move, and the combustion gas comes into the guiding tube and pushes the traction head to burst out the guiding tube, and the traction head drives the capture net to open. The combustion gas piston type movable guiding tube netting device has a quick expansion speed, and the area of the expansive capture net is big.

A pollution-free liquid balancing device comprises a sealing bag (), a front cover (), a rear cover () and liquid balancing matter (), wherein the sealing bag (), the front cover () and the rear cover () are all plastic material. The sealing bag () is filled with the liquid balancing matter () inside, and plastically sealed under high temperature at both ends. The diameters of the front cover () and the rear cover () are matched with the inner diameter of a launch barrel (), and the sealing bag () is provided between the front cover () and the rear cover (). In an ordinary transportation state, the liquid balancing matter () is well sealed in the sealing bag (), and a missile is launched forward by the propulsion of powder during launch, the sealing bag (), the front cover () and the rear cover () crack instantaneously, and the liquid balancing matter () is ejected backward outside the barrel at high speed. The forward and backward impulses are similar or equal, thereby reducing or eliminating the impulse to the launch barrel () during launch. The device has a simple structure and uses the pollution-free liquid balancing matter (), thus there is no pollution after launch.

Systems and methods allow for intercepting a small, low-altitude and low-velocity target. A system includes a detecting apparatus, a directing control apparatus, an aiming control apparatus, a launch control apparatus, a launching device, and an intercepting device. A method includes: searching and tracking a target by the detecting apparatus in a networking mode, or by the aiming control apparatus in a single-soldier mode; sending target information to the launch control apparatus; performing a trajectory calculation by the launch control apparatus; and launching the intercepting device by the launching device to intercept the target. A low-cost system with a short response time can thus be realized. The target falls with the net at a low velocity under a parachute, and this is desirable in a city environment.
