Abstract

The conventional method in target noise simulation which generally applied for verifying signal processing algorithm always use CW or LFM signal plus with pseudo-random sequences. But the reality target which has numerous machines complicates the radiated noise with propulsion, control, and habitability. Oceanic acoustics channel and target itself acoustic signature makes it more complex. This paper research on the characters of two basically different noise spectrum types which are continuous spectrum and line spectrum, and build two models mentioned above which based on target acoustic signature, sailing condition, and time-frequency statistical regularity. Simulation proved the validity of method which can apply to the hardware in the loop simulation, hardware system test, and underwater ordnance simulation.
