Embodiment Construction

[0051] figure 1 is a schematic diagram of the relationship between the ground tracking antenna pointing and the relative position of the target.

[0052] The present invention comprises steps:

[0053] ① Deduce the specific mathematical expression of the compensation matrix;

[0054] The relationship between the ground tracking antenna and the target is shown in the accompanying drawing (1) of the specification. For the two-dimensional tracking antennas of the TE11 mode and TE21 mode, regardless of the influence of the system error, the sum and difference branch signals are respectively expressed as:

Abstract

The invention discloses an error matrix compensation method of a monopulse tracking receiver system, relating to compensation for system errors in a two-dimensional self-tracking system in the field of communication. The method comprises the following steps: analyzing the reason causing the error of the tracking receiver system; obtaining a system error compensation matrix through formula deduction; measuring and analyzing a large amount of test data to determine specific parameters of the compensation matrix; and finally introducing the compensation matrix into a ground digital tracking receiver to eliminate the system error. The method has the characteristics that the equipment is simple, the use and maintenance are convenient, the performance is stable and reliable and the like; and the method is especially suitable for a two-dimensional tracking receiver in a measurement and control system for the measurement and control of unmanned aerial vehicle and the like.

Description

technical field [0001] The invention relates to a monopulse tracking receiver system error matrix compensation method in the field of communication measurement and control, and is particularly suitable for a single-channel monopulse tracking receiver in an antenna two-dimensional self-tracking system. Background technique [0002] In the field of communication measurement and control, the system error of the tracking receiver in the antenna self-tracking system mainly includes the introduction part of the antenna and the introduction part of the channel equipment. For a one-dimensional tracking tracking receiver, it is only necessary to adopt the radio frequency cable phasing method for the channel part to remove the system error. This phasing process is simple, and the tracking index can meet the system requirements. For two-dimensional tracking tracking receivers, it is difficult to meet the requirements of the system only by channel RF cable phasing method. Due to the lar...
