    • This system and method provides a direction finding system that enables modern RF DF systems to analyze short duration signals in the entire instantaneous bandwidth. By providing a method to process wideband data, the invention drastically improves throughput and probability of intercept (POI). The invention is unique in that it does not require separate narrowband channels for analysis, and can simultaneously calculate azimuth and elevation estimates for every frequency in the bandwidth of an incident signal. It is also well-suited for fixed point, FPGA implementations making it a perfect match for modern state-of-the-art processing systems. The system and method capitalizes on the ability of Fourier Frequency Transform operations to accurately resolve incident wave phase at discrete frequencies. The system then uses the phase information from the individual elements in the array to arrive at an emitter azimuth angle. The azimuth angle is nearly simultaneously used in concert with lookup tables of all possible elevation angles to compare the arrival time delay between the array elements to determine emitter elevation angle.
    • 该系统和方法提供了一种方向发现系统,其使得现代RF DF系统能够在整个瞬时带宽中分析短持续时间信号。 通过提供处理宽带数据的方法,本发明大大提高了吞吐量和拦截概率(POI)。 本发明是独特的,因为它不需要单独的窄带信道用于分析,并且可以同时计算入射信号带宽中每个频率的方位角和高程估计。 它也非常适合固定点,FPGA实现使其成为现代最先进的处理系统的完美匹配。 该系统和方法利用傅里叶频率变换操作精确地解决离散频率入射波相位的能力。 然后,系统使用来自阵列中的各个元件的相位信息来达到发射器方位角。 方位角几乎同时用于所有可能仰角的查找表,以比较阵列元件之间的到达时间延迟,以确定发射器仰角。

    • Method and a device for automatic selection of a better starting gear in a vehicle, including the steps of engaging a first starting gear, on driver demand controlling propulsion torque as to attempt to achieve a first take off, if the first starting gear is too high interrupting the first take off and automatically braking the vehicle, engaging a second adapted starting gear which is a lower gear compared to the first starting gear, controlling propulsion torque as to attempt to achieve a second vehicle take off, and if the second vehicle take off attempt results in a transmitting of torque to driven wheels of the vehicle being enough as to perform a take off then stop braking the vehicle. An incorrectly selected starting gear can thus be automatically changed. The starting gear change can be performed in an uphill situation.

    • A Method and Apparatus for Detecting the Presence and Locations of Radio Controlled Improvised Explosive Devices in Real Time. The system will clandestinely detect the presence and location of RCIED's along roadways in real time. This “RCIED Street Sweeper” system consequently allows its users to remove the explosive devices, pre-detonate them, or simply avoid the location so that the weapons cannot be used against a convoy or other important target. The system has the abilities (disclosed in U.S. patent application Ser. No. 10/829,858) to conduct fast wideband scanning of the RF spectrum looking for ambient RF signals as well as RCIED leakage signals. Furthermore the system has the ability to correlate the received leakage signals with the ambient RF signal environment, in order to verify authenticity. Still further, the system has the ability to continually mark and record the precise map location where each of those RF spectrum measurements emanated, including the relative distances between them. Still further, the preferred system will calculate adjusted curve profiles given the real time distance data. Fifth, the preferred system needs to have the ability to correlate sets of trend data with the adjusted curve profiles to determine matches. Further yet, the system alerts the vehicle driver to the presence and location of any RCIED that is detected by the system. Finally, the system is capable of being installed in a low profile, clandestine manner on a mobile platform such as a car or truck, so as not to alert insurgents of its existence.

    • A Method and Apparatus to Perform Surgical Reactive Jamming while Maintaining Simultaneous Tactical Communications is disclosed. The system provides an enhancement to surgical reactive jammers that combines near-real-time jamming capability with the additional feature of allowing tactical communications. The tactical communications transmissions are compressed and packetized such that they can be broken up and transmitted during the jamming system's look-through periods. This approach facilitates listening during these look-through periods (not only for EW emitters, but also for friendly communications signals). The system should allows for talk during these look-through periods (“talk-through” periods). Such a system is unique in that it can automatically calculate the best frequency for a surgical reactive jammer to use against enemy targets as well as providing a fully secure tactical communications link which is synchronized with other units in the field. This invention is therefore vital to the interests of United States national security as it provides a valuable Electronic Warfare capability.
    • 公开了一种在维持同时战术通信的同时执行手术反应干扰的方法和装置。 该系统提供了将近实时干扰功能与允许进行战术通信的附加功能相结合的手术反应干扰器的增强。 战术通信传输被压缩和分组化,使得它们可以在干扰系统的浏览周期期间被分解和传输。 这种方法有助于在这些浏览期间(不仅用于EW发射器,而且用于友好的通信信号)。 系统应允许在这些浏览期间(“通话”期间)进行通话。 这样的系统是独一无二的,因为它可以自动计算手术反应干扰器用于敌方目标的最佳频率,以及提供与现场其他单位同步的完全安全的战术通信链路。 因此,本发明对美国国家安全的利益至关重要,因为它提供了有价值的电子战能力。
