摘　　要：为了有效衡量多波束测深系统的目标探测性能,提高舰船水下目标搜寻、援潜救生和打捞能力等,对当前多波束测深系统目标探测问题进行分析,推导了多波束测深系统目标探测分辨率估计模型。以SONIC 2024型多波束测深系统为例,分析了不同水深下在多波束测深系统垂直航迹方向、沿航迹方向分辨率的变化规律及量级大小,对覆盖宽带和航速等参数指标设置提出了合理建议,为多波束测深系统目标探测能力的准确评估提供依据,具有一定参考价值。In order to effectively measure the target detection performance of MBES and improve the ship’s underwater target search,submarine rescue and salvage capabilities,the current MBES target detection problems are analyzed,and the multibeam target detection resolution estimation model is derived.Taking the SONIC 2024 MBES as an example,Analyzes the change rule and magnitude of the multibeam horizontal and vertical resolution in different water depths,and puts forward reasonable suggestions for the setting of parameters such as coverage bandwidth and speed.The accurate evaluation of the system’s target detection capability provides a basis and has certain reference value.
