摘要

FIELD: physics.;SUBSTANCE: group of inventions relates to electromagnetic compatibility (EMC) of an integrated radioelectronic system (RES) and can be used to evaluate its efficiency when operating in conditions of unintended interference (UI) in the interests of providing EMC. Method of estimating efficiency of an integrated radioelectronic system under conditions of unintended interference is that based on determination of current set parameters for transmission and reception of each radioelectronic device (RED) integrated into RES, processing of UI in receivers (REC) of RED, arriving via channels "antenna-antenna", is performed, decision is made to overcome UI threshold levels and technical condition (TC), in which RED is located, after which electromagnetic environment for RED is evaluated in accordance with expression determining , depending on measurement and where is total time of UI action, which exceeded specified threshold of detection in k^th realization of j^th cycle of i^th RED functioning; is the time interval of exceeding the threshold of the a^th UI, which does not intersect on the time interval with other UIs, where is the time (interval) of operation of the i^th RED for reception in the j^th cycle of functioning; is the time interval of exceeding the threshold by the g^th group of UI, presented through - vector-line - of the time moments of the end of the UI of the g^th group, and - vector-string of - moments of time beginning of g^th group UI, where w_b is the number of UIs mutually crossing in time in the b^th group. Evaluation of the efficiency of radioelectronic devices is carried out based on TC analysis of radioelectronic equipment (three possible states: - operable condition, state of temporary failure and state of complete failure of the i^th (j^th, k^th) RED), and the RED efficiency indicator, which is determined by the probability probability of the i^th RED of the assigned tasks in the UI action conditions, where R_i (j) is total number of cycles of i^th RED in j^th cycle of RES operation; further, based on the RED priorities (reflected by the importance factors c_i), evaluating the efficiency of the integrated RES, which does not require taking into account all possible versions (combinations) of the RED technical states based on the P_RES (K, N, j) potential RES performance of their tasks; here N is the number of RED integrated into the RES. System implementing method according to claim 1, it includes interface-input-output module (500), special computer (SC) of RES (400), modules for evaluation of RED (501, 502, 503) efficiency. Each of modules consists of antenna device (AD), receiver (REC), measuring device (MD), special computer (SC) of RED. At inputs 1, 2, 3 AD₁ (101), 13, 14, 15 AD₂ (201), … , 27, 28, 29 AD_i (301) receive UI in form of and and their accounting is carried out depending on time t by corresponding main, bypass and outband signal transmission channels. System also comprises SC RES (400) for calculating the probability P_RES RES potential perform assigned tasks under the action of UI; from outputs 1, 2, 3 of data input-output module (500), values of parameters vectors T, q, and C are transmitted, results of measured intervals of action of such UI and - are supplied from outputs 7 of MD₁ (103), 16 of MD₂ (203), … , 24 MD_i (303) to inputs 10 SC₁ (104), 20 SC₂ (204), … , 34 SC_i (304), where their accumulation and processing takes place (obtaining further information on the obtained values is transmitted to inputs 35, 36, … , (i + 34) SC (400), where probability of P_RES is calculated; result in the form of efficiency of all RED and efficiency RES P_RES is issued to consumer; listed devices, except RED (REC and AD), are combined into hardware-software system (504). Implementation of the proposed invention will make it possible to assess efficiency of integrated RES operating under conditions of unintentional interference, adequately and accurately taking into account contribution (importance) of each RED.;EFFECT: based on the obtained estimate, it is possible to make decisions in the interests of providing EMC of radioelectronic complexes.;2 cl, 10 dwg, 5 tbl
