Design and Implementation of Hardware-in-the-loop Simulation Environment in Scaling Multi-Target and Multi-Jamming of Torpedo

The underwater scaling multi-target identification has become an important index for evaluating acoustic countermeasure capability of modern torpedo homing system, but the relative sea trial circumstance is difficult to con-struct. Based on the analyses of target validity judgment and shelter calculation for scaling multi-target, a real-time sig-nal generation algorithm is designed, and a hardware-in-the-loop simulation system is constructed. Simulation of scaling multi-target and multi-jamming environment is conducted with the system. The test results prove that the proposed sys-tem can meet the needs of relational simulation.
