| 摘要: |
| 针对低RCS（radar cross section）的隐身舰船很难被普通的单基地雷达探测到的问题，提出了采用非合作多基地雷达系统对海上目标进行探测，创建了一个海上场景，其中多艘商船在S波段（3 GHz）发射电磁波，作为机会雷达；一艘护卫舰大小的军舰作为雷达系统接收机，目标假定为一艘货船和一艘隐身军舰。采用专业的电磁软件对海上目标进行仿真，计算普通货船和隐身军舰的双基地RCS数据，建立了MATLAB仿真模型，研究了非合作多基地雷达的探测覆盖范围。使用FEKO的双基地RCS仿真表明，通过改变发射机的数量和发射机到接收机之间的距离，找到一种最优的多基地雷达系统几何结构和系统配置。 |

| Abstract: |
| Aiming at the problem that stealth ships with low RCS （radar cross section） are difficult to be detected by ordinary monostatic radars, a non?cooperative multistatic radar system is proposed to detect sea targets. A maritime scene is created, in which multiple merchant ships emit electromagnetic waves in the S?band （3 GHz） as opportunistic radars. A frigate?sized warship acts as a radar system receiver, and the targets are assumed to be a cargo ship and a stealth warship. The professional electromagnetic software is used to simulate sea targets, and the bistatic RCS data of ordinary cargo ships and stealth warships are calculated. The MATLAB simulation model is established to study the detection coverage of non?cooperative multistatic radar. The bistatic RCS simulation using FEKO shows that an optimal multistatic radar system geometry and system configuration are found by varying the number of transmitters and the distance from the transmitter to the receiver. |
