    • A Direction Finding Method and System Using Probabilistic Mapping is disclosed. Also disclosed is a preferred system that employs a technique for taking in data sets (lines of bearing) from DF receivers and characterizing those signals with their respective probabilities of error. Then using a unique method, the preferred system can display the triangulated position on a map with an overlay of probability fields indicating the emitter location with varying levels of confidence. Even further, the preferred system is able to redraw the probability fields on the map display in real-time as new data is collected and updated. In this way, a far more efficient EL System has been achieved in which the emitter's position can be determined more quickly. It should be noted that with this invention, triangulation can be done with just a single (mobile) DF Set in the EL System. Today's systems for triangulation must use at least three DF Sets.
    • 公开了使用概率映射的方向查找方法和系统。 还公开了一种优选的系统,其采用从DF接收机接收数据集(方位线)的技术,并用它们各自的误差概率表征那些信号。 然后使用独特的方法,首选系统可以在地图上显示三角测量位置,其中概率域的叠加指示发射器位置具有不同的置信度。 更进一步地,优选的系统能够在收集和更新新数据时实时地重新绘制地图显示上的概率域。 以这种方式,已经实现了更加有效的EL系统,其中可以更快地确定发射器的位置。 应当注意,通过本发明,可以在EL系统中仅使用单个(移动)DF组来进行三角测量。 今天的三角测量系统必须使用至少三个DF集合。

    • A Method and System for Optimizing Decibel Data Conversion. This invention provides an ability to convert linear signals into decibel units via digital logic circuitry. The resultant system can present information to users in real-time. This is made possible by performing an approximation function that is simple enough to be implemented directly in digital hardware, rather than through software executed by massive computing resources. An exemplary application for this technology is as a component of a surgical reactive electronic jamming system. This invention allows a surgical reactive jammer to determine precisely the correct jamming thresholds to apply in real-time. It allows signal surveillance equipment to survey the spectrum and display those results in dBm with far more efficiency than before. Finally, it enables a whole industry of communications related devices that need to do real time decibel conversion.

    • A System and Method to Autonomously and Selectively Jam Frequency Hopping Signals in Near Real-time is disclosed. The system and method to autonomously and selectively jams frequency-hopping signals in near real-time. The present system is able to react within a millisecond or less. The system and method incorporates a fundamental change in the detection and reaction technology, this system and method having a reaction time that is short enough to capture and then jam even the fastest frequency hopping radios in use today, without relying on prior art methods of using standard CPU driven technology. The system has the ability to automatically detect short duration signals (such as those output from frequency hoppers), to automatically determine if detected signal(s) should be jammed, and subsequently to automatically and extremely quickly activate the jamming transmitter on the frequency-hopper transmitter's frequency. Finally, the system provides a programmable user interface so that operators can set up the system to act autonomously as intended, such that operator intervention is unnecessary when the system is placed in jamming operation mode.
