With the rapid development of general aviation,the low altitude,slow speed,and small(LSS)targets represented by unmanned aerial vehicles(UAV)has undergone profound changes in terms of quantity,technological means,and campaign mode.As a result,the threat capability of LSS target continues to increase,and the security and prevention needs become increasingly urgent.In this paper,a detection and disposal system(DDS)for the LSS in urban scene is presented based on the analysis of domestic existing problems,which construct a trinity prevention and control system by nimble command and control system(C2S),multiple detection,and multiple disposal.In the DDS,as the core of the system,the C2S is used to realize the integration of the whole system;the all-weather,all-aerospace and round-the-clock warning network are constructed by the multi-sensors;the multilayered stereoscopic defense system are constructed by the “soft” and “hard” means.Integrating LSS target prevention into the field of information-based warfare,it has stronger system confrontation ability and meets the requirements of future information warfare.
