The emitter's&nbsp;processing gain (time bandwidth product) is&nbsp;large and is much larger than the noncooperative intercept receiver's processing gain. The large processing gain of the emitter comes from coding the transmitted waveform with a code that is unknown to the intercept receiver.&nbsp;In addition, a low power waveform transmission, an ultra low side lobe antenna and scan modulations that are confusing also contribute to a low probability of intercept emitter. These methods of LPI design are complex especially when they are combined into a single piece of hardware. Increased capability can also be achieved by networking two or more of these emitters together for a covert battlefield surveillance. This has a major impact of the waveforms that are used and the receiver signal processing used in each emitter. </SPAN> Fri, 02 Jan 2009 02:50:47 +0100
