Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present invention belong. The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments of the present invention.
The invention designs an Automatic Identification System (AIS) of a wide-area military ship, the core of which is a time-frequency division hybrid multiplexing technology, and the AIS is mainly characterized in that: the AIS divides each minute into 2250 time slots, each AIS communication device in the AIS applies for a transmission time slot in a reserved manner, and each AIS communication device can randomly select one communication channel from a predetermined number of communication channels corresponding to the current transmission time slot as a current transmission channel for transmitting data.
Each AIS communication device in the existing civil AIS broadcasts its own ship information in a self-organized time division multiple access (SOTDMA) manner, and surrounding ships realize autonomous collision avoidance by receiving the broadcasted information. The ships in the civil AIS are limited by the visibility condition, the number of the participated AIS communication equipment is limited, and the smaller time slot collision probability can be ensured in an SOTDMA mode. However, in military applications, AIS has a wide monitoring demand, and AIS communication equipment is often mounted on military aircraft, military sphere platforms, and the like to extend the monitoring range. Under the condition, due to the fact that time slot multiplexing exists among the AIS communication devices of the ships, the AIS communication devices in the air receive a plurality of AIS signals in the same time slot, and therefore received signal collision is caused, and the receiving probability is reduced.
In order to reduce the risk and improve the success rate of receiving AIS signals by air AIS communication equipment, the invention adds a plurality of communication channels on the original civil AIS system, and meanwhile, the AIS communication equipment adopts digital multi-channel processing to realize the capability of simultaneously receiving the signals of the plurality of communication channels, thereby forming the wide-area military AIS with time division and frequency division hybrid multiplexing. In the AIS, after a ship acquires self information and forms a periodic broadcast message to be sent, time slots are reserved and allocated according to a civil SOTDMA mode, 1 communication channel is randomly selected from a plurality of preset communication channels to be sent on each sending time slot, the probability of signal collision received by the time slots is reduced through the randomness of communication channel selection and the characteristic that AIS communication equipment receives signals of the plurality of communication channels at the same time, and the monitoring capacity and the monitoring range of a system are remarkably improved.
The wide-area military AIS provided by the invention can accurately analyze the collision signals received by the air AIS communication equipment, and can enable the air AIS communication equipment to accurately monitor and identify a large-range sea area in real time. The wide-area military AIS provided by the invention does not need a complex antenna unit, has low requirements on software and hardware, has low requirements on installation conditions on a platform, and has strong military practical value.

Therefore, K received by the air AIS communication equipment in AISB-1 AIS signal collision probability of
According to K received by air AIS communication equipment in AISB-1 AIS signal collision probability of
A predetermined number F of communication channels per time slot in a predetermined unit time can be determinedB。
Exemplarily, 150 AIS communication devices are arranged in the AIS, namely, one AIS communication device is arranged on each of 149 ships, and one AIS communication device is arranged in the air, so that the design is needed to meet the requirement that when each AIS communication device on the 149 ships sends an AIS signal to the air AIS communication device, the collision probability of each AIS signal is not more than 0.05.I.e. PB＝0.05，KB＝150，N＝2250，C B10, according to
The predetermined number F of communication channels corresponding to each time slot in the predetermined unit time can be calculatedB. Wherein, CBThe average number of time slots may be used in a predetermined unit of time by all AIS communication devices counted in advance.
Further, F corresponding to the current transmission time slotBOne of the communication channels is randomly selected as a current transmission channel.
S400: transmitting the current AIS signal over the current transmit channel.
Further, after the current transmission time slot and the corresponding current transmission channel are determined, the current AIS signal is sent through the current transmission time slot and the corresponding current transmission channel.
