Granted: 2003-10-20
Abstract: FIELD: radio communication realized by means of channels with frequency modulation of signals. SUBSTANCE: transmitted data are converted to sequence of blocks with length of k symbols. Then test blocks with length of k symbols are formed by coding of above- mentioned blocks with coding speed 1/2. Given process differs from known methods in that modified relative coding is carried out before frequency modulation. In this case intervals of constant frequency exceeding four symbols are impossible in transmission of series of zeros or units of any length. At receiving side k symbol information and test blocks are formed from received 2k symbol modified relative code after frequency demodulation. Thereupon k symbol syndrome is computed, corresponding k symbol error locator is found in table formed by criterion of likelihood maximum. Located errors are corrected by way of bit-serial summing of locator symbols by XOR and of symbols of received information block. EFFECT: enhanced communication noise immunity in channels with frequency modulation. 1 cl

Title: Adaptive seismic correlation object direction finder
Inventor: KRJUKOV I N
IPC: G01S3/80
Filed: 2003-06-19
Granted: 2005-03-10
Abstract: FIELD: protection aids. 
     SUBSTANCE: direction finder can be used for taking azimuth relatively guarded objects at guarded areas, calculating number of objects in group target and classifying found objects. Direction finder has two seismic receivers, two processing channels with delay lines and correlators, maximal signal selector, correlator, testing module, commutator and calculator. To realize the direction finding function the method of passive diversity detection and ranging is used. The main information criterion for finding direction to object has to be the function of mutual signals correlation in two signal processing channels. Value of azimuth is judged from value of signal delay. Change in value of signal delay is equivalent to controlling directional diagram of seismic active aerial which allows classifying detected objects separately. Test influence is used for adaptation of speed of propagation of seismic wave which changes under influence of meteorological conditions. Current value of speed of propagation of seismic wave is judged from time of delay of test influence signal coming to second seismic receiver. Tuning of lines of delay is conducted correspondingly to those changes. 
     EFFECT: improved precision of direction finding.
