Abstract

The invention discloses a pulse modulating system of a radar system. The pulse modulating system of the radar system comprises a signal input / output port, a signal conversion circuit, a pulse generating module and a drive module, wherein the signal input / output port is used for receiving commands of a radar processor and feeding back data, the signal conversion circuit is used for converting command control level signals sent from the radar processor into 3.3 VTTL level signals needed for the pulse generating module and converting the 3.3 VTTL level signals fed back from the pulse generating module into level signals capable of being identified by the radar processor, the pulse generating module is used for sending pulse signals with variable amplitude, pulse width and frequency according to commands sent from the radar processor, and the drive module is used for driving an MOSFET module to output a high-voltage large-current pulse modulating voltage after amplifying the pulse signals. The pulse modulating system of the radar system is convenient to regulate the pulse modulation conduction time and the pulse repeating frequency of an active emitting circuit and an active receiving circuit of an active phased array radar according to the use needs.
