TL;DR: In this paper, the authors present a generalization of the likelihood ratio test for MIMO radar, which is used for target localization in clutter-free environments, as well as to evaluate the performance of a single-input single-out (SISO) system with multiple-output (MISO) receivers.

TL;DR: In this article, the effects of noise reflected back from the transmitter to the receiver and the application of moving target indication to FMCW radars are considered, as well as the strengths and weaknesses of the system and how the weaknesses can be mitigated.
Abstract: Frequency modulated continuous wave (FMCW) radar uses a very low probability of intercept waveform, which is also well suited to make good use of simple solid-state transmitters. FMCW is finding applications in such diverse fields as naval tactical navigation radars, smart ammunition sensors and automotive radars. The paper discusses some features of FMCW radar which are not dealt with in much detail in the generally available literature. In particular, it discusses the effects of noise reflected back from the transmitter to the receiver and the application of moving target indication to FMCW radars. Some of the strengths and weaknesses of FMCW radar are considered. The paper describes how the strengths are utilised in some systems and how the weaknesses can be mitigated. It also discusses a modern implementation of a reflected power canceller, which can be used to suppress the leakage between the transmitter and the receiver, a well known problem with continous wave radars.

TL;DR: In this paper, radar is discussed in the context of a multiple-input multiple-output (MIMO) system model and examples are given showing that many traditional radar approaches can be interpreted within a MIMO context.
Abstract: In this paper, radar is discussed in the context of a multiple-input multiple-output (MIMO) system model. A comparison is made between MIMO wireless communication and MIMO radar. Examples are given showing that many traditional radar approaches can be interpreted within a MIMO context. Furthermore, exploiting this MIMO perspective, useful extensions to traditional radar can be constructed. Performance advantages in terms of degrees of freedom and resolution are discussed. Finally, a MlMO extension to space-time adaptive processing (STAP) is introduced as applied to ground moving-target indication (GMTI).

TL;DR: In this paper, the effects of slowly moving targets as they appear in the output of an airborne coherent side-looking synthetic aperture imaging radar are considered, and two approaches to airborne moving target indication (AMTI) are summarized.
Abstract: This paper considers the effects of slowly moving targets as they appear in the output of an airborne coherent side-looking synthetic aperture imaging radar. The image of a moving reflector is described, and two approaches to airborne moving target indication (AMTI) are summarized. It is shown that the effects of target movement are decreased as the radar scan rate is increased, and are increased as the (Doppler processed) compression ratio is increased.
