Abstract

The invention belongs to the technical field of radar emission signal generation and especially relates to an on-line-reconfiguration-type broadband / narrowband general radar source and a generation method thereof. A digital unit, a general radar signal generation platform, can generate broadband / narrowband signals, of which the parameters, such as frequency, bandwidth, time width and modulation form, are variable according to requirements of the whole radar machine. The universality of the radar source is improved; the radar source is allowed to have good portability and expandability; change of multi-mode multi-frequency and multi-waveform composite parameters and the like of radar work can be finished by configuring different parameters online and without changing core hardware; development cost is saved; and development risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of radar transmission signal generation, and in particular relates to an on-line reconstruction type wide / narrowband universal radar source and a generation method thereof. Background technique [0002] With the development of modern electronic countermeasures technology, the electromagnetic environment of targets that radars need to deal with is becoming increasingly complex, especially the identification of unknown air conditions is more urgent. Radars not only need to intercept and track targets, but also need to classify, identify and monitor targets. Imaging, at the same time, should have the ability to quickly respond to the battlefield situation and switch to the appropriate working mode; and with the expansion and upgrading of radar development models, it is necessary to develop various corresponding supporting radar sources, which has resulted in high development repetition and waste of resources Th...
