摘要： A follower aircraft is guided to a lead aircraft using a datalink that determines range between the two. The lead aircraft has an antenna array and processing system for determining azimuth/elevation of the follower aircraft. The lead aircraft transmits a ranging message to the follower aircraft and stores a lead aircraft time of transmit (TOT) time. The ranging message is received at the follower aircraft and a follower aircraft time of reception (TOR) time is stored. A second ranging message is transmitted from the follower aircraft to the lead aircraft and a follower aircraft TOT time is stored. The second ranging message is received at the lead aircraft and a lead aircraft TOR is stored. A message is sent from the follower aircraft when follower aircraft TOT and TOR. The range and time offset is determined by the lead aircraft using follower aircraft TOT/TOR and stored lead aircraft TOT/TOR.

摘要： A method and apparatus for signal acquisition with transmit blanking compensation compensates for collisions between a desired received signal and a transmitted signal. A blanking block blanks a received signal when the transmitted signal is transmitted and stops blanking when the transmitted signal stops to provide a received signal with blanking. A correlation block correlates the received signal with blanking with a known sequence of symbols corresponding to the desired received signal and outputs a correlation metric and a number of symbols blanked. Means for adjusting the correlation metric or a variable threshold using the number of symbols blanked are provided. A decision block compares the adjusted correlation metric to a fixed threshold or the correlation metric to the variable threshold. If the adjusted correlation metric exceeds the threshold or if the correlation metric exceeds the variable threshold, the decision block determines that the desired signal is detected.

摘要： The present invention is directed to accurate GPS (global positioning system)-free relative navigation between an unmanned aerial vehicle (UAV) and a tanker aircraft. The UAV transmits a signal which is received by an antenna array at the tanker aircraft. Horizontal relative position of the UAV is determined by calculating range and bearing based on time and phase differences in the received signal. Vertical relative position of the UAV is determined by comparing the altitude of the UAV with the altitude of the tanker aircraft. The tanker aircraft then transmits a navigation solution based on the relative position of the UAV which is received by the UAV. The UAV may utilize the navigation solution transmitted by the tanker aircraft as a backup to a GPS determined navigation solution, in a GPS denied scenario, or in combination with an INS (inertial navigation system) determined navigation solution.

摘要： An apparatus and method for signal separation and SINR improvement is disclosed. In particular, disclosed is an iterative technique whereby a noisy signal, that may include signals from one or more distinct emitters, is first improved through an SINR improvement technique. Next, one signal from the noisy signal is identified and a reference signal substantially free of noise and interference is generated for this signal, and then this reference signal is subtracted from the noisy signal. This process is repeated until no other signals may be identified. In this way, the signal with the highest SINR may be identified first and then removed from the original signal. As such, the identified signal is no longer present as interference for the remaining signals, thus improving each of the remaining signals' respective SINRs.
摘要翻译：公开了一种用于信号分离和SINR改进的装置和方法。特别地，公开了一种迭代技术，其中可以包括来自一个或多个不同发射器的信号的噪声信号首先通过SINR改进技术得到改进。接下来，识别来自噪声信号的一个信号，并为该信号产生基本上没有噪声和干扰的参考信号，然后从噪声信号中减去该参考信号。重复该过程，直到不能识别出其它信号。以这种方式，可以首先识别具有最高SINR的信号，然后从原始信号中去除。因此，所识别的信号不再作为对剩余信号的干扰而存在，从而改善了每个剩余信号的各自的SINR。

摘要： The present invention is a method and system for estimating interference. Packet characteristics of relevant packets within the channel at a given point in time may be processed. For example, a power level, occupied frequency and corresponding time references may be accumulated and stored for each relevant packet within the channel at a given point in time. As each packet is processed for demodulation, the channel samples, at which interference occurred, may be appropriately weighted based on the packet characteristics. Advantageously, the nature of the interfering channel traffic may be measured to properly de-weight the interference in a computationally efficient manner.

摘要： The present disclosure is directed to a system and method for providing directional spectral awareness via an antenna system which includes a single parasitic antenna and a processor, the processor being communicatively coupled with the parasitic antenna. The antenna system allows for quick scanning of all sectors included in a plurality of sectors of an RF environment being monitored by the antenna system. The antenna system also allows for monitoring sectors of interest. The directionality of the parasitic antenna of the antenna system may reduce interference and multipath along with providing improved SNR due to antenna gain, thereby allowing for collection of signals of interest in a more favorable environment, thereby enabling analysis such as frequency and spatial use, signal detection, signal identification, and source geolocation to succeed when it may have failed if an omni-directional antenna were used.
