Abstract: Systems and methods of the disclosure can implement intrusion radiation protection (IRP) to prevent malicious IP traffic in a secure network. The IRP system can receive an IP packet, determine that a protocol of the IP packet matches a predetermined policy of a plurality of predetermined policies, classify the IP packet based on the predetermined policy and a size of the IP packet, inspect a payload of the IP packet responsive to the classification to determine features of the IP packet, determine that one of the features of the IP packet is improper based on the classification, and flag the IP packet as suspect based on the determination. The IRP system can log and/or drop the flagged IP packet. The IRP system can additionally replace a payload of the IP packet with a second payload, and transmit the IP packet with the second payload to its destination.

Abstract: A system and method of digital beamforming for a monobit phased array radar system includes providing a plurality of monobit analog signals received by at least one antenna to at least one field programmable gate array (FPGA). A plurality of monobit SerDes transceivers within the FPGA convert the plurality of monobit analog signals into a plurality of multibit digital signals, each of the multibit digital signals being modified according to a digital signal conditioning value to calibrate, phase align, and synchronize the digital signals. A digital beam is formed by coherently combining the plurality of digital signals within the FPGA.

Abstract: Devices and methods of providing response pulses in response to threat pulses are general described. The threat pulses are detected, identified and validity determined using reprogrammable firmware. Threat pulses are extracted from memory and the amplitude, frequency, phase, length and timing modified to generate a coherent set of superposed response pulses in response to the threat pulses. The modifications are calculated in situ using parameterization, rather than being based on tables. Multiple response pulses in response to different threat pulses are simultaneously generated, combined and transmitted in a single channel. Partial pulse capability and the capability to create a weighted and modulated composition of multiple response pulses is provided.

Abstract: Method and apparatus for leakage signal cancellation in a simultaneous transmit and receive RF system includes: generating a digital transmit signal for transmission from the system; receiving a receive signal produced by reflection of the transmit signal from an object or generated by a second RF system; adaptively filtering the transmit signal by an adaptive finite input response (FIR) filter; calculating filter coefficients for the adaptive FIR filter in real-time at a different sampling rate; adaptively inputting the calculated filter coefficients to the adaptive FIR filter to generate a cancellation signal in real-time; and applying the cancellation signal to the receive signal to cancel leakage in the receive signal to generate an optimum receive signal.

Abstract: Method and apparatus for tracking pulse trains from one or more emitters. For a valid pulse, PRI parameters are measured. A pulse pattern count is incremented and checked to determine if a track is acquired for the emitter.
