    It is in the time domain that significant differences in jamming effects are to be seen between conventional and spread spectrum radar waveforms. A conventional radar pulse has a time-bandwidth product of around unity whereas a spread spectrum pulse has a time-bandwidth product typically in the range 10 to 100. This paper considers two types of spread spectrum waveform, the linear frequency chirp ... View full abstract»

  • Randomly interrupted random waveforms

    This paper describes the application of randomly interrupted random waveforms in multi-mode radar systems. The work has been motivated by its application to synthetic aperture radars. Conventional SARs use a pulsed waveform, which sets upper limits on the swath width and the cross-range resolution of the SAR. It may be possible to exceed these limits by using a random waveform. In a monostatic sys... View full abstract»

    The Doppler resolution of a radar is determined by the total coherent integration time, which in turn is constrained by the target decorrelation time. When target or platform speed is very high, as is the case in spaceborne applications, the decorrelation time may be very short, and Doppler resolution poor. In addition, the shape of the radar's response in the range/Doppler plane is determined by ... View full abstract»

    Racal-Thorn, Wells (formerly Thorn EMI Electronics Limited) have been involved in radar signature measurements at Wells in Somerset. Since 1979 the Full-scale Trials Group (FST) have designed and developed mobile radar systems for full-scale dynamic measurements of military platforms in land, sea or air environments. The paper describes the digital processor systems (DPS) hardware designed and bui... View full abstract»

    Reports progress in an investigation of wide bandwidth waveforms giving improved range resolution but with discontinuous spectra. The objective is to have a signal occupying a large section of the HF band, but interrupted at several frequencies where other uses are present. The main reasons for using a discontinuous spectrum is to prevent the radar transmissions from disrupting other users and to ... View full abstract»
