DEVICE FOR DETERMINATION OF OBJECT SPACE ORIENTATION Russian patent published in 2015 - IPC G01S5/02 

FIELD: instrumentation.

SUBSTANCE: additional modulators, summation unit and demodulator are used. Additional modulation of the signal from each element of antenna array is made by own code modulation sequence, and formation in summation unit of the single, group signal is made, the signal is processed in single receiving channel, this excludes errors due to non-identity during use of several receiving channels and several analogue-digital converters. Group signal division to signal from each of N elements of the antenna array is made at low frequency during digital processing in the demodulator. The received signals are analysed for interferences and their exclusion from the group signal by forming the minimum sensitivity of the direction pattern of the antenna array in the direction of interferences reception.

EFFECT: increased accuracy of determination of space orientation of the object by means of use of the full signal energy from each of N elements of the antenna array within entire measuring range due to creation of the single group signal.
