Constant voltage source system applied to radar

Abstract

The invention discloses a constant voltage source system applied to radar. The constant voltage source system comprises a constant voltage source system body, a controlled source, a first multichannel reselecting switch, a controller and a second multichannel reselecting switch, wherein the constant voltage source system body comprises a plurality of constant voltage sources with different electrical parameters; the controlled source is connected to an input end of the constant voltage source system body; one end of the first multichannel reselecting switch is connected the controlled source, and the other end of the first multichannel reselecting switch is selectively connected to the input end of the at least one constant voltage source in the constant voltage source system body; the controller is connected to the controlled source through a PWM adjusting circuit, and the controller is further connected to the first multichannel reselecting switch; one end of the second multichannel reselecting switch is selectively connected to an output end of the at least one constant voltage source in the constant voltage source system body, and the other end of the second multichannel reselecting switch is connected to the controller. By means of the constant voltage source system, switching between the constant voltage sources with the different electrical parameters and simultaneous power supplying of the multiple constant voltage sources with the multiple electrical parameters are efficiently achieved.

Description

technical field [0001] The invention relates to the technical field of radar equipment, in particular to a constant voltage source system applied to radar. Background technique [0002] Radar uses radio to find targets and determine their spatial positions. Therefore, radar is also called "radiolocation". Radar is an electronic device that uses electromagnetic waves to detect targets. Its information carrier is radio waves. The principle is that the transmitter of the radar equipment sends electromagnetic wave energy to a certain direction in space through the antenna, and objects in this direction reflect the electromagnetic waves encountered. The radar antenna receives the reflected wave, sends it to the receiving device for processing, and extracts some information about the object (the distance from the target object to the radar, the distance change rate or radial velocity, azimuth, height, etc.). [0003] Each circuit includes a power supply circuit part. The voltage...

Problems solved by technology

In some circuit test systems or power supply circuits, the voltage of various electrical parameters needs to be continuously changed. At this time, multiple power supplies are required to cause waste of resources and low switching efficiency.
