Passive radar polarization automatic compensation system and method

Abstract

The invention relates to a passive radar polarization automatic compensation system. The system comprises a system test and control unit, a radar scanning signal generation unit, a radar receiving andsignal processing unit, a compensation data real-time storage unit and a data analysis and processing unit. The invention discloses a design method of the passive radar polarization automatic compensation system. The design method comprises steps of step 1, initializing a polarization compensation system; step 2, collecting compensation original data in real time; step 3, exporting the original data; step 4, carrying out original data preprocessing and parameter extraction; and step 5, carrying out compensation data writing. The method is advantaged in that aiming at requirements of large-range, wide-band and full-polarization multi-dimensional compensation of a radar, the system provides a technical feasible solution and implements the technical feasible solution to achieve an obvious effect.

Description

technical field [0001] The invention relates to the compensation of the polarization characteristic of the passive radar, and is especially suitable for the zero position full polarization compensation and the two-dimensional plane compensation of the polarization characteristic of the missile-borne passive radar seeker. Background technique [0002] The polarization domain is another available information resource besides information in the time domain, frequency domain, time-frequency domain, time spectrum domain, and air domain. Any kind of polarized wave can be decomposed into a pair of components of orthogonally polarized waves. [0003] Radar calibration is an indispensable technical preparation work from the development and production of radar to the range test. Among them, in the polarized radar receiving system, the imbalance of the polarized receiving channel, the cross-polarized component in the polarization characteristics of the single-polarized antenna, and th...

Problems solved by technology

[0006] Existing passive radar polarization compensation technology generally adopts manual or semi-automatic operation. The whole process needs to coordinate the synchronous cooperation among multiple instruments and equipment such as signal source, seeker, turntable, polarizer, power supply, etc. The test process is complex and repetitive. Strong

[0007] 1) Manual operation is time-consuming and labor-intensive, and is easily affected by the proficiency of personnel;

[0008] 2) Conventional network port serial port semi-automatic compensation technology, large amount of data, slow interface rate, time-consuming, and prone to errors and broken links
