Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
Example 1
A radar countermeasure equipment performance real-time detection system is disclosed, as shown in fig. 1 and fig. 2, and comprises a radar countermeasure equipment, a radar signal calibration source and a main controller, wherein the radar countermeasure equipment, the radar signal calibration source and the main controller are connected through a wired or wireless network, for example, in the real-time detection system shown in fig. 1, the radar countermeasure equipment is connected with the main controller through a wired network, and the main controller is connected with the radar signal calibration source through a wireless network.
The main controller issues a radar signal radiation command to the radar signal calibration source through system main control software, the radar signal calibration source receives the radar signal radiation command through an antenna, then radar signals with different parameters are generated through a radar signal generator, and working parameters of the generated radar signals are fed back to the main controller in real time.
The system main control software is provided with a data input or lead-in interface, and a plurality of working parameters of the radar signals to be radiated are manually input or led in the main controller, so that the continuous radar signals to be radiated are conveniently formed.
The radar countermeasure equipment reconnaissance the radar signal generated by the radar signal calibration source, and the radar countermeasure equipment carries out sorting processing to form a pulse data stream and sends the pulse data stream to the main controller.
The main controller compares the parameters of the radar signals fed back by the radar signal calibration source and the radar signals detected by the radar countermeasure equipment to obtain an evaluation result, and an evaluation model is only needed to be carried out according to the existing evaluation standard, which is not the content protected by the invention.
Because the radar signal calibration source and the radar countermeasure equipment are unstable in work at the initial startup time, the radar signal calibration source and the radar countermeasure equipment are started up before performance detection is carried out, so that the radar signal calibration source and the radar countermeasure equipment work for more than 30 minutes, and the accuracy of a detection result is ensured.
It should be emphasized here that, in the industry, the parameter comparison between the radar signal generated by the radar signal calibration source and the radar signal actually detected by the radar countermeasure equipment is directly performed, and the problem of the deviation between the radar signal actually generated by the standard signal generation equipment and the radar signal required to be generated is completely ignored.
Because the radar signal output by the radar signal calibration source is fed back to the main controller in real time, the working parameters of the radar signal generated by the radar signal calibration source can be reserved more timely and accurately. The main controller adopts the radar signal output by the radar signal calibration source rather than the working parameters of the radar signal in the radar signal radiation instruction, so that the influence of a little deviation between the radar signal actually generated by the standard signal generating equipment and the radar signal required to be generated on a performance detection result is avoided.
In order to facilitate parameter comparison, the main controller stores the radar signals fed back by the radar signal calibration source and the working parameters thereof, and the radar signals and the working parameters thereof in the pulse data stream sent by the radar countermeasure equipment as a structured data file.
Two groups of radar signals, working parameters and evaluation results thereof can be directly and visually output, so that detection personnel can conveniently and visually observe evaluation conditions and know the evaluation results.
Example 2
The necessity of the radar countermeasure equipment performance real-time detection system provided by the present invention is demonstrated below by way of specific examples. The data in table 1 are the detection results of the existing radar countermeasure equipment detection method, and the data in table 2 are the detection results of the radar countermeasure equipment real-time performance detection system provided by the invention.
TABLE 1
TABLE 2
Comparing table 1 and table 2, it can be seen that there are some deviations between the radar signal to be radiated (i.e. the radar signal generated by the radar signal calibration source) and the radar signal to be radiated (i.e. the radar signal actually generated by the radar signal calibration source) on different parameters, for example, each parameter of the radar signal to be radiated is frequency 380MHz, pulse width 10 μ s, pulse repetition period 1000 μ s, and output power 10dBm, each parameter of the actual radar signal to be radiated is frequency 380.03MHz, pulse width 10 μ s, pulse repetition period 1000.10 μ s, and output power 9.86dBm, and each parameter of the actual radar signal to be detected is frequency 379.96MHz, pulse width 10.01 μ s, pulse repetition period 1000.01 μ s, and output power 9.5dBm.
Therefore, if the parameters of the actual reconnaissance radar signal are directly compared with the parameters of the radar signal to be radiated, the accuracy of the evaluation result of the radar countermeasure equipment is affected. The radar signal output by the radar signal calibration source is fed back to the main controller in real time, so that the working parameters of the radar signal generated by the radar signal calibration source can be reserved more timely and more accurately. The main controller adopts the radar signals output by the radar signal calibration source instead of the working parameters of the radar signals in the radar signal radiation instruction, so that the influence of a small deviation between the radar signals actually generated by the standard signal generating equipment and the radar signals required to be generated by the standard signal generating equipment on a performance detection result is avoided.
It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art and related arts based on the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention.
