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.
