[0018] The present invention is described in detail below in conjunction with the accompanying drawings:

[0019] like Figure 1 As shown: a power supply system of a radar system, including a mains power supply module, an AC to DC module, a second switch, a charging module, a battery module, a first switch, a voltage stabilizing circuit, a third switch, a boost circuit, a buck circuit, a control acquisition system and a pulse emission source;

[0020] The AC power supply module is connected to the AC-DC module, wherein the AC-DC module converts the AC power output by the AC power supply module into DC power and reduces the 220V voltage to 12V;

[0021] The AC-DC module is connected to the voltage stabilizing circuit via the second switch, the AC-DC module supplies power to the voltage stabilizing circuit and the second switch is used to control power supply and power failure;

[0022] The charging module is connected to the battery module, wherein the charging module continuously charges the battery module;

[0023] The battery module is connected to the voltage stabilizing circuit via a first switch, the battery module supplies power to the voltage stabilizing circuit and the first switch is used to control power supply and power failure;

[0024] The voltage stabilizing circuit is connected to the voltage boosting circuit via the third switch, so that the voltage stabilizing circuit supplies continuous power to the voltage boosting circuit;

[0025] The boost circuit is connected to the pulse emission source, and the boost circuit supplies power to the pulse emission source;

[0026] The voltage stabilizing circuit is also connected to the voltage step-down circuit, and the voltage step-down circuit is connected to the third switch through the control acquisition system.

[0027] In the present invention, the charging module is a charging circuit, which is mainly used to charge the battery module, wherein it meets the 3C charging requirements and can be charged quickly. The first switch and the second switch are both mechanical switches, which can control the power supply and power off of the entire device.

[0028] The AC to DC module is an AC to DC circuit, which is a conventional circuit. It can convert the 220V AC power supply module output by the mains power supply module into DC and step it down to 12V to power the system.

[0029] The voltage stabilization circuit is mainly used for voltage stabilization of the battery module.
