Case study on low probability of recognition (LPR) radar using GSM

A practical investigation of the application of low probability of recognition (LPR) to Global System for Mobile Communications (GSM) systems within radar waveform design is provided. LPR radars focus on deceiving electronic support (ES) receivers by selecting waveforms which emulate the waveforms of communication transmitters and thus provide an additional mechanism to achieve covert operation. The advantages and drawbacks of different levels of LPR are analysed from both the radar and ES-receiver perspectives. Some LPR techniques have only a minor effect on radar performance while requiring vastly more complex ES systems to address, and vice versa. This means that both radar and ES systems must be considered when evaluating LPR techniques.
