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.
