Abstract

The invention discloses a small generalized dual-frequency continuous wave transponder, which can be equipped with different radio frequency channel transceiver front ends on the basis of the same general module to meet different application requirements, and realizes the miniaturization and integration of the dual-frequency continuous wave transponder. Universal. The invention is a small generalized dual-frequency continuous wave transponder mainly composed of a general module and an optional module, the general module mainly includes a digital processing circuit, a frequency source circuit and a power conversion circuit, and the optional module mainly includes a radio frequency channel transceiver front end. Among them, the universal module improves the integration and versatility by adopting configurable radio frequency agile transceiver chip and phase-locked frequency source, and the optional module can be replaced as a whole or not assembled according to different requirements. By adopting the small generalized dual-frequency continuous wave transponder of the present invention, the product development cycle can be significantly shortened, and the high-precision measurement requirements of different types of high-dynamic targets can be quickly adapted.

Description

technical field [0001] The invention relates to the technical field of aerospace measurement and control communication equipment, in particular to a small-sized generalized dual-frequency continuous wave transponder. Background technique [0002] Dual-frequency continuous wave transponders are generally loaded on high-dynamic carriers such as rockets and satellites, and work together with ground measurement and control equipment to continuously track and measure carrier targets and obtain high-precision measurement elements. With the development of aerospace technology, the launch and flight tests of various new aircraft are becoming more frequent, the demand for high-precision measurement of targets is becoming more and more urgent, and the application of dual-frequency continuous wave transponders is also becoming more and more extensive. There are various types of existing dual-frequency continuous wave transponders, and the radio frequency interfaces and corresponding an...
