description system and method for secure communication of collected amphibious data is disclosed, which uses direct-sequence, spread spectrum, ultra wideband (DS-SS UWB) communications to enhance the security of the collected amphibious data during transmission over a wireless communication link. The UWB technique used transmits the collected data using very short pulses with low duty cycles. Thus, the power of the transmitted signals can be distributed evenly over a large bandwidth, and buried within the environmental noise (below the noise floor) to produce "stealth" transmissions. The transmitted signals can also be encrypted, which provides a wireless data communication transmission that is immune from jamming and masked from eavesdropping attempts. As one example, a system for secure communication of collected amphibious data is disclosed, which includes a DS-SS UWB transmitter and receiver. The DS-SS UWB transmitter includes a data input unit, a data encryption unit, a UWB encoder unit, a DS spectrum spreader function unit, and a power amplifier unit. The DS-SS UWB receiver includes a receiver front end unit, a data decryption unit, a DS spectrum despreader function unit, and a receiver filter unit. As another example, the DS-SS UWB transmitter and receiver are combined to provide a DS-SS UWB transceiver.
