Abstract: A hybrid electronic warfare and communications system (EW/COMM) eliminates the space, power, weight, and cost of a dedicated communication system by exchanging messages with other nodes in a network as phase modulations of radar jamming signals. Some embodiments impose message phase modulations onto CW jamming signals, while other embodiments interleave message phase modulations with pseudorandom phase modulations of the jamming signals. Message chip rates can be matched to pseudorandom phase modulation chip rates. Messages are thereby obfuscated as either phase noise or random phase modulation of the jamming signals. Messages can be encoded as BPSK or QPSK modulations. Messages can be preceded by pre-established headers known to other nodes, and distinguished thereby from random noise modulations. Some embodiments include a dedicated COMMS module and/or antenna, while other embodiments implement the communications function mostly or entirely in software. Messages can be encrypted before transmission and decrypted after reception.

Abstract: A hybrid RADAR and communication system provides both RADAR and wireless communication (COMMS) that share the same antenna, transmit and receive amplifiers, and other hardware, thereby reducing size, weight, and power requirements. In embodiments, COMMS implementation only requires adding additional software to a RADAR system. Embodiments are EW/COMMS systems that provide electronic warfare and wireless communication. EW/COMMS embodiments facilitate communication in hostile environments by enabling data exchange at any frequency within a broad EW frequency range. Communication signals can be obfuscated by interleaving them with EW waveforms at the same RF frequency. Collaborative communication between EW systems is enhanced by reducing EW communication lag times. Systems with physically distinct broadband and narrow band receivers can negotiate data exchange timing and frequencies by exchanging low power, low data rate control signals that are detected by the broadband receiver, while subsequent high density data bursts are received by the narrowband receiver.
