摘要： An interference cancellation system (ICS) may be used with a communication system to prevent or minimize interference from one or more sources. The ICS may receive radio frequency (RF) signals comprised of one or more signals of interest (SOI) and multiple interfering signals. An interference estimation processor (IEP) may be used to estimate the one or more interfering signals. The interfering signals may be estimated using spatial and/or time diversity, which may be combined with statistical methods. The estimated interfering signals may be sent to the ICS, which may use the estimated interference signal to cancel the interference and output the SOI.

摘要： A communication system includes an omnidirectional antenna to receive a wideband primary signal, a nulling antenna to receive a secondary signal and a controller. The nulling antenna is oriented to place a null in a direction of a desired communication signal and the controller subtracts a processed secondary signal from a processed wideband primary signal to produce a jamming cancelled signal.

摘要： A secure communication system is provided for transmitting a country specific frequency allocation in encrypted form between a host processor and a remote device. The secure communication system comprises a host processor and a remote device capable of communicating with the host processor over a communication link. The host processor has a plurality of stored data sets and a predefined encryption algorithm. Each one of the stored data sets comprises a country specific frequency allocation. The remote device has a unique identifier code and also has the predefined encryption algorithm. Responsive to the unique identifier code, the host processor provides a selected one of the plurality of data sets in encrypted form by utilizing the predefined encryption algorithm. The unique identifier code provides an encryption key for the predefined encryption algorithm. The remote device then decrypts the encrypted data set using the predefined encryption algorithm with the identifier code as a decryption key.

摘要： Code-domain spread spectrum (CDSS) correlation embodiments for wireless and radar transceivers with the dual purposes of in-band jammer rejection and transmitter-to-receiver self-interference suppression. The encode/decode schemes may be employed at different locations on the TRx paths such as TRx front-end and/or in the baseband, for different TR transceiver architectures such as I/Q TRx, MIMO/phase array TRx and polar TRx. The encoder may be placed in the baseband digital unit and the decoder may be placed in front-of-the LNA in the RF domain for easy encoder implementation in the digital domain while protecting the receiver path from interferences. Group delay filters and/or tunable time delays can be employed to compensate for a signal path delay in a radar TRx. Signals coded with a correlated code sequence and synchronized with the encoder in the transmitter may be decoded and restored at the receiver while the in-band jammers and self-interference can be suppressed.

摘要： A system and method for conducting electronic warfare on a target site includes the use of a small unmanned aircraft system (SUAS) having a fuselage and a Prandtl wing, wherein at least two electric ducted fans are positioned on the fuselage. A power system of the SUAS has a plurality of hydrogen fuel cells positioned within the Prandtl wing. An electronic warfare payload is carried by the fuselage, wherein the electronic warfare payload and the at least two electric ducted fans are powered by at least a portion of the plurality of hydrogen fuel cells. During an operation, the SUAS may launch near an IAD site and initiate an electronic warfare effect on an integrated air defense site with electronic warfare payload carried by the SUAS to interfere with at least one surface-to-air missile (SAM) system.
