ufeffsystu00e9m multistaticku00e9ho surveillance primary radar for monitoring objects (102) detecting and monitoring the moving air, sea and ground objects based on coherent signal processing and signal or signals from them odrau017eenu00fdch and / or reference signals u010dnu00edch,including the receiver and / or receiver (103) of the reference signal or signals (1011) in controlled or uncontrolled transmitter and / or transmitters (101) and further reflected signal or signals (1002) from objects (102) originating from the same source.and, on the other hand, further comprising communication means (1003) for the distribution of information about the detected objects (102) of the receiver and / or receivers (103) to a central processing unit (104), which is based on the principle of bistaticku00e9ho radar, where the transmitting and receiving side are in this system, spatially separated,when the reflectivity material occurs on its surface as a target signal from the transmitter and continuous component of the reflected signal in the direction of the receiver is detected by the antenna, and by analogy with the odrau017eenu00e9mu signal is coherent in time received direct signal from vysu00edla zhejiang or this generated on the side of the receiver.the target is on the side of the receiver is detected on the basis of the correlation between the direct and reflected ray signal from the target or reference the difference times income, both signals, and the thus obtained difference defines the surface of the rotary ellipsoid with outbreaks in point transmitter e and receiver on which the target is located and at the same time, it is for the target doppler frequency shift resulting from the reflection signal determined from the target.while the result is determining the position and speed of the target.part of the system's transmitter containing antenna assembly (210), which is connected the input channel (2100) for analogue signal processing block (220), and then through the generator (230) signal, on the other hand, to the management and control unit (240) and on the other hand, at the same time, the block (250). nchronizace,where this block (250) is connected, on the one hand, to the synchronization (260) receiving gnss (global navigation or surveillance system) signal and, on the other hand, through a two-way communication channel (2300) to the management and control unit (240) connected communication line (2400) or (1003) data np t (or network time protocol)the individual blocks are modular to allow adaptation to the different parameters of the transmitter.
