Description
本公开涉及(但不限于)毫米波成像技术领域。
现在毫米波成像技术已经有了很大的突破，得到了越来越广泛的应用，但是针对毫米波阻止技术的研究相对较少。毫米波阻止技术大多应用于军工行业，而民用行业几乎没有使用毫米波阻止技术。
随着毫米波成像技术的不断发展和人们对成像需求的不断提高，近年来毫米波成像技术越来越多的应用于安检、医疗、导航和交管等领域。由于毫米波成像技术具有高分辨率、高精度的特定，因此可以对近距离物体进行高分辨率的三维立体成像。如果该技术被应用到个人身体或者面部成像，则会导致个人隐私泄露。
发明内容
根据本公开实施例，提供一种阻止毫米波建模成像的方法，包括：通过对接收的电波进行检测，确定周围设备是否发射了毫米波；当确定周围设备已发射毫米波时，通过对所述毫米波进行分析，获得毫米波特征；以及根据所获得的毫米波特征，生成并发射相应的干扰毫米波，以便阻止周围设备用毫米波建模成像。
根据本公开实施例，提供一种阻止毫米波建模成像的装置，包括：确定模块，其设置为通过对接收的电波进行检测，确定周围设备是否发射了毫米波；获取模块，其设置为当确定周围设备已发射毫米波时，通过对所述毫米波进行分析，获得毫米波特征；以及发射模块，其设置为根据所获得的毫米波特征，生成并发射相应的干扰毫米波，以便阻止周围设备用毫米波建模成像。
根据本公开实施例，提供一种计算机存储介质，其上存储有一个或多个程序，所述一个或多个程序被一个或多个处理器执行时，所述一个或多个处理器执行根据本公开的阻止毫米波建模成像的方法。
附图用来提供对本公开实施例的进一步理解，并且构成说明书的一部分，与本公开的实施例一起用于解释本公开，并不构成对本公开的限制。在附图中：
图1是根据本公开实施例的阻止毫米波建模成像的方法流程图；
图2是根据本公开实施例的阻止毫米波建模成像的装置示意图；
图3是根据本公开实施例的阻止毫米波建模成像的系统示意图；以及
图4是根据本公开实施例的阻止毫米波建模成像的方法的示例流程图。
以下结合附图对本公开的实施例进行详细说明，应当理解，以下所说明的实施例仅用于说明和解释本公开，并不用于限定本公开。
毫米波成像方案包括主动式和被动式两种，本公开提供的阻止毫米波成像方法针对主动式成像方案，这是因为主动式成像方案适用的场景更广泛，成像效果更好，针对该方案进行阻止更有实用价值。
图1是根据本公开实施例的阻止毫米波建模成像的方法流程图。
如图1所示，根据本公开实施例的阻止毫米波建模成像的方法可以包括步骤S101至S103。
在步骤S101，通过对接收的电波进行检测，确定周围设备是否发射了毫米波。
在步骤S102，当确定周围设备已发射毫米波时，通过对所述毫米波进行分析，获得毫米波特征。
在步骤S103，根据所获得的毫米波特征，生成并发射相应的干扰毫米波，以便阻止周围设备用毫米波建模成像。
毫米波特征可以包括频率、频宽、幅度、调制方式以及发射功率。在一个实施例中，步骤S103可以包括：根据所获得的全部毫米波特征，生成与所述毫米波的波形相同且功率较大的干扰毫米波；以 及发射所生成的干扰毫米波，以便阻止周围设备用毫米波建模成像。在另一个实施例中，步骤S103可以包括：根据所获得的部分毫米波特征，生成与所述毫米波的波形相同且功率较大的干扰毫米波；以及周期性地发射所生成的干扰毫米波和预置的噪声干扰信号，以便阻止周围设备用毫米波建模成像。
在一个实施例中，通过对所述毫米波进行分析未获得毫米波特征时，可以发射预置的噪声干扰信号，以便阻止周围设备用毫米波建模成像。
上述实施例提供了针对主动式毫米波成像方案的阻止方法，该阻止方法稍加修改就可以对被动式毫米波成像方案进行阻止。在被动式成像方案中，成像设备接收机主自身发射的毫米波，所以，如果没有侦测到对方设备发射的毫米波，那么对方设备有可能在使用被动方案对机主进行建模成像，此时可以发射类似身体发射的毫米波，以阻止对方设备成像。
图2是根据本公开实施例的阻止毫米波建模成像的装置示意图。
如图2所示，根据本公开实施例的阻止毫米波建模成像的装置可以包括：确定模块201，其设置为通过对接收的电波进行检测，确定周围设备是否发射了毫米波；获取模块202，其设置为当确定周围设备已发射毫米波时，通过对所述毫米波进行分析，获得毫米波特征；以及发射模块203，其设置为根据所获得的毫米波特征，生成并发射相应的干扰毫米波，以便阻止周围设备用毫米波建模成像。
在一个实施例中，发射模块203可设置为根据所获得的全部毫米波特征，生成与所述毫米波的波形相同且功率较大的干扰毫米波，并发射所生成的干扰毫米波，以便阻止周围设备用毫米波建模成像。在另一个实施例中，发射模块203可设置为根据所获得的部分毫米波特征，生成与所述毫米波的波形相同且功率较大的干扰毫米波，并周期性地发射所生成的干扰毫米波和预置的噪声干扰信号，以便阻止周围设备用毫米波建模成像。
在一个实施例中，所述发射模块203还可设置为，通过对所述毫米波进行分析未获得毫米波特征时，发射预置的噪声干扰信号，以 便阻止周围设备用毫米波建模成像。
图3是根据本公开实施例的阻止毫米波建模成像的系统示意图。
如图3所示，根据本公开实施例的阻止毫米波建模成像的系统可以包括侦测器模块、信号分析处理模块、干扰决策模块以及干扰信号发射模块。
侦测器模块周期性地检测是否有设备正在发射毫米波对机主进行建模成像。如果存在，则接收该毫米波，并通知信号分析处理模块对信号进行处理。
信号分析处理模块对接收到的毫米波信号进行分析处理，以解析出该毫米波的频率、频宽、幅度、调制方式和发射功率，然后把分析结果传送给干扰决策模块。
干扰决策模块根据信号分析处理模块分析的结果来决定采取哪种干扰策略。如果正确地解析出毫米波的频率、频宽、幅度、调制方式和发射功率，则采用瞄准式干扰策略(即，发射相同波形的干扰毫米波)；如果仅仅检测到了毫米波并没有检测到其具体特性，则采用阻塞式干扰策略(即，在很宽的频带上发射噪声干扰信号)；如果检测到了毫米波的一部分特性，则可以采用结合上述两种干扰策略的混合干扰策略。确定了干扰策略后，干扰决策模块可以通知干扰信号发射模块发射干扰毫米波和/或噪声干扰信号。
干扰信号发射模块根据干扰决策模块的决定来发射相应的干扰毫米波和/或噪声干扰信号，进行成像阻止，以保护用户隐私。
图4是根据本公开实施例的阻止毫米波建模成像的方法的示例流程图。
如图4所示，该示例流程可以包括步骤S401至S405。
在步骤S401，侦查对方发射信号。可以周期性地侦查检测对方发射的毫米波信号。
在步骤S402，判断是否检测到对方发射的毫米波信号。可以分析判断是否有毫米波信号正在对机主进行建模成像，如果没有，则返回步骤S401；如果有，则进入步骤S403。
在步骤S403，对发射的毫米波件信号分析处理。
若检测到了对方发射的毫米波信号，则对侦查到的毫米波信号进行详细的分析。
在步骤S404，根据对信号分析处理的结果来选择不同的干扰策略。
在步骤S405，发射相应的干扰毫米波和/或噪声干扰信号。
根据本公开各实施例，接收对方设备发射的毫米波，通过对接收到的毫米波进行信号分析处理，然后发射相应的干扰毫米波，从而阻止对方设备进行毫米波成像。如果能够正确的分析出对方设备发射毫米波的频率、频宽、幅度、调制方式和发射功率，则可以采用瞄准式干扰策略，即，发射波形相同的干扰毫米波，同时发射功率大于对方；否则可以使用阻塞式干扰策略，即，在很宽的频带上发射噪声干扰信号。此外，也可以混合采用上述两种干扰策略达到最佳的阻止建模成像效果。
根据本公开实施例提供的方案，不仅仅可以用来保护个人隐私，在有毫米波建模成像的各种场所，如果有必要都可以使用该方法阻止毫米波成像。
