Technical field
The utility model relates to the marine radar technical field, particularly a kind of marine radar detection system.
Background technology
Marine radar is the basic guarantee means of navigation safety.In the use of marine radar, according to the setting of range setting and working status parameter, the detection performance of radar can corresponding as requested change.These can adjust the working status parameter that can be provided with: the pulse width of radar signal and pulse repetition rate, gain and bandwidth that signal receives, the parameter setting that various input are handled and target following is handled in the ARPA radar terminal.The quality of radar observation performance depends on these working status parameter, but these working status parameter of present marine radar, to all targets in the observing environment around the radar all is identical, the characteristic that does not have differentiation ground response different target is not carried out comprehensive optimization to detecting performance and resolution performance and detection performance and tracking performance yet.Therefore, the performance adjustment of marine radar at present can only be considered total general requirement, maybe can only consider to adapt to the observation requirement of part target, and the detection performance of radar is not given full play of like this.
Technical progress along with marine radar, the embedding of the further modularization of radar transceiver, the further computerize of ARPA radar terminal, FPGA/DSP provides more strong signal processing platform, make the standardization more of ARPA radar system, software implementation, universalization, have more opening, these all make ARPA marine radar system have stronger information processing capability and control ability flexibly.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the purpose of this utility model is to propose a kind of object-orientedly and have the marine radar detection system of adaptive ability, to improve the target detection performance of marine radar, gives full play to the security effectiveness of marine radar.
To achieve these goals, the technical solution of the utility model is as follows: a kind of marine radar detection system, comprise radar antenna, radar receiver, radar transmitter and ARPA radar terminal, described radar antenna is connected with radar receiver, radar transmitter respectively by transmit-receive switch, and described ARPA radar terminal is connected with radar receiver, radar transmitter and radar antenna respectively by signal cable; Described radar transmitter has data transmission interface, can receive steering order, can outputs state detection data; Described radar receiver has data transmission interface, can receive steering order, can outputs state detection data; Described ARPA radar terminal has self-adaptive detection and handles and Control Software, can send duty to the wave filter of input in radar transmitter, radar receiver and the ARPA radar terminal and target following processing instruction is set.
Radar transmitter described in the utility model has data transmission interface, handles the instruction of sending with Control Software according to the self-adaptive detection of ARPA radar terminal, changes the pulse width and the recurrent interval that transmit; Described radar receiver has data transmission interface, handles the instruction of sending with Control Software according to the self-adaptive detection of ARPA radar terminal, changes gain and bandwidth that signal receives; It is that echoing characteristics is analyzed, calculated the echo character parameter, adopts based on detecting and following the tracks of that mutual correlation filter is realized tracking processing, the evaluating target mass parameter of the detection processing of signal and target, the duty of setting up object-oriented radar transmitter, radar receiver and ARPA radar terminal is provided with instruction that the self-adaptive detection of described radar terminal is handled function with Control Software.
Compared with prior art, the utlity model has following beneficial effect:
1, the detection performance of marine radar depends on the setting of ARPA radar terminal duty, preset the working status parameter adjustment of being done according to range setting and state parameter, ARPA radar terminal duty can only be generally adjusted, and the different echoing characteristicss of each objectives can not be adapted to.Because the utility model is according to the analysis of each different target echoing characteristics, land or water front echo, the far and near different target echoes such as boats and ships of size are set up characteristic parameter, to the given target quality parameter of echo through input and target following processing, on this target azimuth, determine that the multipulse sequence array mode of radar target acquisition and ARPA radar terminal detect and the filtering parameter of following the tracks of correlation filter thus.The resolution performance that the burst pulse of radar emission signal is convenient to obtain, broad pulse and high pulse repetition frequency help improving detectability, the multiple-pulse that has nothing in common with each other with pulse width and recurrent interval constitutes the combined detection sequence that transmits, at the target acquisition detection performance of different qualities and the complex optimum of resolution performance and detection performance and tracking performance, constitute object-oriented self-adaptation marine radar detection system with different multiple-pulse array modes.
2, because the utility model has been taked result object-oriented, that follow the tracks of according to target property and target detection, adjust the parameter of Filtering Processing in radar transceiver state and the ARPA radar terminal, therefore the utility model can be at concrete different target, between the resolving power and precision of target detection performance and target measurement, between the tracking performance of target detection performance and target, obtain complex optimum.Present marine radar or rely on broad pulse to improve detection performance and reduce the resolving power and the precision of measurement, or the resolving power that relies on burst pulse to improve to measure and precision and reduce detection performance, do not respond the differential characteristic of target, also do not consider simultaneously the interactivity between input and the target following, the utility model has then overcome this limitation.
3, the basic task of radar is to find target and measurement target, and the key property of radar depends on the echoed signal quality of target, and the signal quality of target depends on the background characteristics of target echo characteristic and noise jamming.The utility model has adopted goal-oriented method, to being in the target in the noise jamming, from the echo character parameter of target to detecting and following the tracks of the target quality parameter of evaluating after the mutual filtering, the evaluation mechanism of based target, in the mutual Filtering Processing of the state setting of radar transceiver and input and tracking, set up adaptive FEEDBACK CONTROL, seek comprehensive optimum detection performance.The transceiver state of marine radar is determined according to being provided with at present, not to change with the different of clutter background according to target, the wave filter that is adopted in the processing of input and tracking is also preset often, lack flexible adaptability, and the utility model has overcome this limitation.
