The device for digital synthesis of a multifrequency linear-frequency-modulated phase-code-manipulated signal in the mode of full-polarization sounding of the space

摘要

The proposed device belongs to the field of radio engineering, and can be used in full polarization radar systems for detection, recognition and selection.;The task for solving the proposed utility model is to expand the functionality of the digital computational synthesizer to form broadband signals with complex modulation types for their emission in two orthogonal polarizations. ;This device, under conditions that occur in practice, allows to achieve the following technical result: providing the formation of multifrequency (with additional frequency modulation by harmonic law) linear-frequency modulated phase-coded (with any given pseudo-random sequence) signals for full-polarization sounding of space.;The technical result in the proposed device is achieved by introducing a harmonic frequency modulation scheme, a phase-code signal manipulation scheme of the signal by a pseudo-random sequence, and introducing a second channel that completely duplicates the first one with the same clock frequency but with different input parameters, orthogonal to the first polarization channel, thereby providing a mode for full polarization sounding of the space.
