Abstract:
    This invention requires a passive allocation methods and systems of low-flying objects, relating to wireless transmission technology field. Establishing a honeycomb-net passive allocation system, the signal which is using CDMA honeycomb-net can work as passive detective signals. Putting a direct devise in CDMA system, magnifying and retransmitting the signals of CDMA basic station, locating the signal-detective devises of CDMA basic station, the detective devises will examine and estimate the signal which is reflected by the objects, determine whether the object is low-flying, then delivering the parameters to the control center memorizer. According to the situation of the parameters received from the control center, the department of locating will establish the quotation of observation and resolve the coordination of the objects. This invention could effectively resolve the problem of the disturbance of the direct-signal from which passive allocation system exerting to transmission signal and the distance effectiveness of the system, also it serves an advantage of the weaken-reflecting of detecting and evaluating, it gains high percentage of successful-allocation of distance objects.
