Description
Technical Field
The invention belongs to the technical field of equipment test identification, and particularly relates to a complex comprehensive environment for radar product reliability verification and a construction method.
Background
The new period equipment test identification work takes the 'actual combat oriented' as the guide, and the basic purpose of finding out the performance and efficiency base of the equipment is taken, so that the actual combat assessment of the equipment is highlighted. The experimental identification of the weaponry should adhere to the actual combat requirement, the performance of the weaponry should be fully tested under various conditions as much as possible, the functional performance assessment under the conditions of complex electromagnetic environment, complex geographic environment, complex meteorological environment, approximate actual combat environment and the like should be highlighted, and the performance of the weaponry should be subjected to 'bottom detection while touching', so that the environmental conditions during the reliability experimental verification should reflect all the characteristics of the products in the field use and task environment as much as possible.
The radar product is used as the 'eye' of weapon equipment, plays a very important role in modern war, and is a key object of attention when the weapon equipment is used for carrying out actual combat assessment. In the process of searching, capturing and tracking targets, radar products face complex physical combat environments and electronic countermeasure environments, such as various active or passive suppressive interferences, deceptive interferences, natural environment influences (such as meteorological clutter and the like), carrier physical environments, product working condition environments and the like.
However, the existing radar product testing environment is difficult to meet the requirements, and in the prior art, the radar product mainly has the following defects in the aspect of reliability test verification close to actual combat assessment:
firstly, the reliability test verification is incomplete in consideration of environmental factors and insufficient in functional performance assessment.
When reliability test verification is carried out on a radar product serving as an important component of military equipment, reliability identification and acceptance test is usually carried out according to the relevant regulations of GJB899A-2009 reliability identification and acceptance test, and the environmental stress in a test section mainly takes vibration stress, temperature stress, humidity stress, electric stress, working cycle and the like into consideration. However, due to the hysteresis of the standard specification, the incompleteness of the test means and the like, only a simple functional performance test is carried out during the period, and the functional performance assessment is insufficient.
Product reliability is the ability to perform a specified function under specified conditions and for a specified time, as specified by the GJB451A-2005 term on reliability maintainability guarantee. Therefore, the environmental conditions of the reliability verification test should reflect the characteristics of the product in the field use and the task environment as much as possible. Furthermore, it is also stated in "reliability identification and acceptance test" of GJB 899-899A-2009 that the combined environmental conditions of reliability identification and acceptance test should be prescribed or agreed by the ordering party, and that the stresses in the test section mainly take into account electrical stress, vibrational stress, temperature stress, humidity stress and product duty cycle in the absence of other provisions by the ordering party.
Compared with the requirement of the equipment test identification work in the new period to highlight actual combat assessment, the current radar product reliability test verification only considers the temperature, the humidity, the vibration, the electric stress and the like, which cannot reflect the task environment characteristics of the product, and cannot meet the assessment requirement of an ordering party, but needs to pay attention to the influence of the complex electromagnetic environment on the product functional performance, and researches a complex environment construction method suitable for the radar product characteristics.
Secondly, various functional performance index tests are carried out on the radar product at different stages, but the verification in the comprehensive environment is not enough.
The radar product carries out various functional performance index tests at different stages, firstly, an indoor near field test of the antenna is carried out, the amplitude/phase distribution, the beam width, the size and the distribution rule of a side lobe of the antenna are preliminarily verified, and the gain of the antenna is estimated; then, on the basis of preliminarily mastering the characteristic parameters of the antenna, carrying out an antenna far field test, and testing the scanning characteristic of the phased array antenna, the receiving/transmitting gain of the antenna, the antenna polarization performance and the like; and secondly, in an external field of a developing party, detecting, tracking a target echo simulation signal sent by a radar target simulator by a radar system, and checking technical indexes such as accuracy and precision of the working process of the radar system. And finally, verifying the functional performance conditions of radar tracking precision, system target capacity, working distance, imaging indexes and the like through the target range test of the ordering party.
The radar product carries out various functional performance index tests at different stages, but it must be seen that in the near-field far-field index test in the previous development process, the environmental adaptability assessment and the reliability index assessment of the product are insufficient, and the identification result of the reliability index cannot be given; in the field test and the target range test, the overall verification of the equipment system is more emphasized, the working time and the fault statistics are limited, the reliability index of the radar product is not specially verified, and the verification test for the environmental adaptability and the reliability of the product lacks special items. For radar products, compared with the requirements of actual combat assessment, the development of test verification of reliability level in a comprehensive environment is still greatly insufficient.
In conclusion, due to the reasons of standard specification lag, incomplete test means, inadequate technical knowledge and the like, the reliability verification environment of the radar product has the problems of incomplete environment type coverage, insufficient comprehensiveness and the like.

And determining physical environment elements causing the fault of the radar product to be detected according to historical data statistics, and constructing a physical environment according to the physical environment elements.
The radar product is influenced by various environmental factors in the whole life cycle, and the related environmental types can be referred to items in standards such as GJB4239-2001 equipment environmental engineering general requirements and GJB150A military equipment laboratory environmental test methods. The influence of various environmental influence factors on the product fault is considered, and the product fault caused by three environmental factors, namely temperature factor, vibration factor and humidity factor accounts for the highest percentage according to historical statistical experience. Generally, radar products can focus on the influence of comprehensive environmental conditions of temperature, humidity and vibration on the reliability of the products according to relevant regulations of GJB899A standards such as reliability identification and acceptance test. The simulation of the environmental conditions of the part can be realized by adopting a temperature-humidity-vibration three-integrated system (with a wave-transmitting window), the environment conditions of temperature, humidity, vibration and the like which can be edited and controlled are provided, and the physical environmental conditions of the product carrier are simulated.
In addition, aiming at the problem of high-power microwave radiation, the invention mainly adopts the methods of arranging a wave-transmitting window between the test box and the microwave darkroom, constructing the microwave darkroom by adopting silicon carbide as a wave-absorbing material and the like.
On the basis of the conventional temperature-humidity-vibration three-integrated system configuration, the requirement of microwave product radiation testing is considered, and the customized requirement is put forward on the design of the test box. The special wave-transparent window design is adopted on the side of the test box where the door is not opened and the heat pipe is not used for air supply, and the wave-transparent window is designed to become a part of the power load darkroom through the switching neck, so that the radiation requirement in the microwave product test process is met. The wave-transmitting window is designed by adopting high wave-transmitting rate and has corresponding power resistance and heat preservation performance. In order to prevent the risk of damaging the tested product caused by microwave radiation reflection, an internal radiation protection structure is adopted inside the test box, and SiC high-power-resistant material is adopted, so that wave absorption is realized, volatile substances are not generated, and the tested product is not influenced.
With the engineering application of the active phased array technology, the radiation power of some radars reaches dozens of kW or even higher at present, and how to construct a complex darkroom meeting the high-power radiation of the radars is also a problem to be focused.
The wave absorbing materials used in the traditional microwave anechoic chamber mainly comprise polyurethane foam absorbing materials, ferrite-polyurethane foam composite absorbing materials and non-woven fabric absorbing materials, and the materials have good wave absorbing performance, but have obvious defects in high power resistance, generally 1.2-3 kW per square meter, and cannot meet the requirement of high-power radiation of radar. In the design scheme, the SiC material is used as the wave-absorbing material, the silicon carbide is tens of times of the traditional material in unit area in comparison with the traditional material in the aspect of high power resistance, and the silicon carbide material is more than 80kW per square meter, so that the requirement of a radar product for carrying out high-power and even full-power radiation performance tests can be met.

The electric stress environmental factors mainly concern the electric stress conditions of the radar microwave products under different working conditions when the radar microwave products execute working tasks, and mainly concern the functional modes, starting characteristics, load conditions and the like of the products. Considering that radar microwave products generate a large amount of heat in the working process, the design of corresponding cooling modes, such as air cooling, liquid cooling and the like, is synchronously developed in the product design process, and corresponding cold source facilities are matched on the carrier. Therefore, when a complex comprehensive environment is constructed, the factors such as a product cooling mode, the temperature and the flow of a cooling medium and the like are simulated by considering the environment with a cold source.

When the radar product is developed to be constructed close to a complex comprehensive environment for actual combat assessment, the suppression interference, the deceptive interference and the combined interference in an electronic countermeasure environment are focused. Wherein the suppressive interference relates to aiming interference, blocking interference and frequency sweeping interference, and amplitude modulation interference, frequency modulation interference and phase modulation interference. The deceptive jamming covers range spoofing, speed spoofing and joint multi-parameter spoofing, as well as both repeater jamming and trail jamming. On the basis, the electronic countermeasure environmental simulation has the capability of combining the suppression interference and the deception interference in a certain proportion to form combined interference.

The part mainly focuses on a passive clutter interference environment consisting of ground clutter, sea clutter and meteorological clutter, and also focuses on regional electromagnetic noise environments such as regional broadcast television signals, mobile communication signals and unintentional interference signals outside a platform as much as possible, and considers the interference influence formed when harmonic waves of the electromagnetic noise environments fall into a radar working frequency band.
