Canonical objects with known radar cross section (RCS), for example, the trihedral corner reflector (TCR), play a crucial role in calibration of automotive sensors. Moreover, these canonical are also used validation simulated RCS obtained using asymptotic methods, such as hybrid geometric optics (GO) and physical (PO) based methods. However, accurate prediction methods is highly dependent on in...

A scheme for multitarget identification and localization using bistatic MIMO radar systems is proposed. Multitarget can be distinguished by Capon method, as well as the targets angles with respect to transmitter and receiver can be synthesized using the received signals. Thus, the locations of the multiple targets are obtained and spatial synchronization problem in traditional bistatic radars i...

The ability to fly an unmanned aircraft regularly and routinely for commercial or civilian applications, in non-segregated, airspace requires a sense and avoid capability. The Mobile aircraft Tracking System (MATS) is a Ground-Based Sense And Avoid (GBSAA) system. The MATS consists of a primary radar, an ADS-B receiver and a transponder interrogator. The Smart Skies project provided an opportun...

Target recognition is the most challenging problem for missile defense. For accurate target recognition discriminant features must be extracted from the target signature. To extract suitable features an optimized waveform is needed which can be generated using pulse compression techniques. Pulse compression is a technique which can be generally used for achieving the benefits of short pulse rat...

We present a hybrid numerical method that combines full-wave analysis with ray-tracing to efficiently model propagation in reconfigurable intelligent surface (RIS)-enabled communication channels. Full-wave simulation is used obtain the radiation pattern of transmitter and complex radar cross section (RCS) RIS. Then, RIS imported into ray-tracer as secondary transmitter. That enables modeling in...

This article proposes a knowledge- and data-driven graph neural network-based collaboration learning model for reliable aircraft recognition in heterogeneous radar network. The recognizability analysis shows that the semantic feature of an is motion patterns driven by kinetic characteristics, grammatical features contained cross-section (RCS) signals present spatial–temporal-frequency (STF) div...

The length and width of insect body are critical parameters for entomological radar species identification. However, the is not measurable in currently. In this study, scattering matrices (SM) 159 specimens were measured using an X-band fully polarimetric laboratory rig a microwave anechoic chamber. relationships between cross-section (RCS) extracted from SM studied. It was found that all these...

In this letter, a design method for low radar cross section (RCS) array antennas based on characteristic mode cancellation (CMC) is presented. Based the theory (CMT), two novel microstrip elements are designed by introducing rectangular slots and slots, which produce 180° scattering phase difference adjusting size of slots. The dominant modes achieve broadband dual-linear polarization CMC simil...

A method for designing a wideband low radar cross section (RCS) antenna is proposed based on hybrid absorptive and diffusive frequency selective reflector (AD-FSR) in this paper. The RCS exhibits manifold responses three artificial bands, which are created by its different components. simple U-slot patch borrowed, integrated with the diffusion metasurface, placed under sheet about quarter wavel...

We are proceeding towards a broadband age both for the communication as well as remote sensing. Recently, CALM standard has already been formulated by ITU with objectives of collision avoidance between car to car as well as car to roadside communication and safety by utilization of Sensor-friendly vehicle. Millimetre wave radar is mandatory in every car to locate accurate position. Lots of work...
