“…Sys-temVue acts as an intermediate stage between simulation world, as in Matlab; and the real implementation world, as in field programmable gate array (FPGA). It can handle range Doppler domain [9]. SystemVue platform simplifies the design and test of Radar/EW systems, while offering a number of key benefits, including the ability to generate complex waveforms for transmitters, receivers and EW system test.…”

As a result of the military's use of synthetic aperture radar (SAR), it has become necessary to use jamming techniques to protect sensitive sites of friendly forces from being intercepted by SAR. To combat SAR sensors, two jamming techniques are typically available: noise jamming and deceptive jamming. In this paper the design and hardware implementation of a proposed active decoy which works as deceptive jamming system, is achieved using field programmable gate array (FPGA). The performance of the developed system is evaluated by SystemVue. 2015.01, using “hardware in the loop” methodology.

“…For this reason, there are many publications that deal with deviations of the real trajectories from the expected one. Examples for this can be found in [20] and [21]. In contrast, this article deals with the sensor movement during a single FMCW ramp measurement and it is assumed that the trajectory of the sensor corresponds to the expected one.…”

Radar imaging using the synthetic aperture radar (SAR) principle is a common method to obtain information about e.g., the surface of a target. However, most image formation algorithms for such systems assume (quasi-)static measurements. This may lead to errors in the processed images if the sensor is moving during the measurement process. This is especially the case for frequency-modulated continuous-wave (FMCW)based sensors since the signal duration is longer than in a pulsed system and the achievable bandwidth is much larger and introduces additional challenges. Motion compensation in the context of radar imaging is usually related to the correction of deviations from an ideal trajectory. In contrast, this article presents a method to take the sensor movement during a single FMCW ramp into account and therefore addresses the effects caused by a continuous path during the transmit/receive process. Hence, faster movement can be achieved during the scanning of the synthetic aperture without being bound by stop-and-go approximations. In addition, it will be shown that the algorithm is suitable to reduce systematic errors due to aliasing caused by spatial sampling below the Nyquist rate. For this purpose, this article presents simulations and measurement results, obtained by an ultrawideband D-band FMCW radar operating between 122 and 170 GHz.
