“…Note that due to the normalisation factors in (7), (10), (14), and (16), the case of standard beamforming (no spatial modulation) realises a response for (18) at t = 0 and β = θ that achieves the maximum value of unity. Thus the 'beam smearing' loss of spatial modulation can be directly determined.…”

Leveraging the recent development of a physical implementation of arbitrary polyphase codes as spectrally wellcontained waveforms, the notion of spatial modulation is developed whereby a time-varying beampattern is incorporated into the physical emission of an individual pulse. This subset of the broad category of MIMO radar is inspired by the operation of fixational eye movement within the human eye to enhance visual acuity and also subsumes the notion of the frequencydiverse array for application to pulsed radar. From this spatial modulation framework, some specific emission examples are evaluated in terms of resolution and sidelobe levels for the delay and angle domains. The impact of spatial modulation upon spectral content is also considered and possible joint delay-angle emission design criteria are suggested. Simulation results of selected target arrangements demonstrate the promise of enhanced discrimination and the basis for the development of future cognitive radar capabilities that may mimic salient aspects of the visual cortex.

“…In contrast, the notion of transmitting different, albeit correlated, waveforms from the elements of an array has been proposed [1][2][3][4][5][6][7][8][9][10][11] as a method to broaden the transmit beamwidth (i.e. beam-spoiling) for the purpose of achieving, for example, simultaneous multi-mode radar [11][12][13][14].…”

“…This velocity corresponds to the speed of a dismounted target or a slowly moving vehicle. At this speed the target will likely be endoclutter, a situation in which along-track interferometry (ATI) may be applied with excellent results [10].…”

In this paper we discuss the frequency-jump burst (FJB) waveform as a candidate for performing joint synthetic aperture radar (SAR) imaging and ground moving target indication (GMTI). We introduce the signal model for simulating SAR data and the method for image formation. The ambiguity function (AF) is used as an analysis tool for determining whether the waveform under investigation has the desired resolution. Image artefacts resulting from target motion are discussed and the degradations are quantified.
