摘要
采用一种简化亮点模型来实现潜艇回波仿真,构造了一个三亮点的回波模型。从仿真结果看,它与单亮点回波模型相比,能更充分地体现潜艇目标回波脉宽展宽和回波脉冲串特性;与六亮点回波模型相比,形式更简化,意义更明确。同时,简化亮点模型的回波特性与实际潜艇回波相吻合,是一种有效简洁的模型。
A simplified highlights model is presented to simulate the echo signal from submarine. It is built by three highlights. The simulation conclusion confirms that the simplified model is an efficient and concise model. Comparing the simplified model with the one highlight model or the six highlights models, the characters of pulse width and pulse trains of echo signal from submarine can be described much better, the model is much simpler and with much more specific meaning.
