Abstract
Description
technical field
[0001] The invention belongs to the technical field of radar systems and is applied in the design of radar frequency synthesizers, in particular to an agile frequency synthesis method compatible with large microwave bandwidth and small intermediate frequency steps. Background technique
[0002] Modern radars need to have strong electronic countermeasures performance, so as to have strong battlefield survivability. Not only does the radar need high precision, but it also requires its small size, light weight, and low power consumption. For the "heart" frequency synthesizer of the radar, its technical index requirements are also more "harsh".
[0003] Direct analog frequency synthesis technology (Direct Frequency Synthesis) uses one or more different crystal oscillators as a reference signal source, and directly generates output signals of many discrete frequencies through frequency multiplication, frequency division, and frequency mixing. Its advantages are h...
