Low probability of detection tactical wireless LAN supporting command and control on the move

Abstract

The current Post Cold War land combat doctrine is geared toward regional conflicts; is focused on power projection; and emphasizes mobility, sanctuary operations, smaller CPs, and C2OTM. Sustaining the intuitive commander and providing the ability to evaluate alternatives, issue orders, and execute within the enemy's decision cycle and beyond his contact range, requires the ability to digitize the battlefield and to own the spectrum. The authors describe a wireless radio based approach which provides for a robust, survivable, very low probability of detection, wide bandwidth LAN interconnect supporting C2OTM for echelons of Brigade and above. They discuss the design and system performance characteristics of an NDI approach based upon a single ASIC chip, fully digital, wideband, spread spectrum demodulator with typical performance parameters of: direct sequence PN spread at rates to 325 M chips/s; real time programmable variable data rates to 325 Mbps; spread spectrum processing gains up to 60 dB; continuous and burst (TDD/TDMA) operation; multiple waveform compatibility (BPSK, QPSK, OQPSK, Bi-BPSK, MSK, CCSK); combined with BER performance within 0.5 dB of theoretical.<>
