Abstract: Test and examination on netted radar systems is a hard nut.Methods and procedures of system integrated test on practical flight verification,simulation experiment by partial object,onsite function examination and monographic test are described,associated with the practice of test and examination on a netted radar system.A creative data process algorithm of detection capability by "region relative enhancing quantity" and a new approach to designing flight verification routes by "informed routes and uninformed routes,fixed height routes and heighten routes,straight routes and maneuver routes" are put forward.The key operation performances of this system,such as detective coverage of all types of targets,intelligence quality and ECCM are tested.It is proved that the integrated methods of test and examination are reasonable and effective.
