The utility model discloses a system for detecting the thickness of the sea ice at the polar region, with very high detection accuracy and efficiency for the thickness of the sea ice. The system comprises a main body with an electromagnetic inductor for sending and receiving the electromagnetic field signal vertical to the sea ice; a sonar device for sending and receiving the sonar signal vertical to the sea ice; a controller connected with the electromagnetic inductor and the sonar device and for calculating the first height between the main body and the lower surface of the sea ice based on the electromagnetic field signal of the electromagnetic inductor and calculating the second height between the main body and the upper surface of the sea ice based on the sonar signal and obtaining the thickness of the sea ice by the first height subtracting the second height; a multi-serials converter respectively connected with the electromagnetic inductor, the sonar device and the controller and for transferring the d
