Microwave imaging of time-varying radar targets
The study deals with the introduction of coherent imaging ideas in the kinetic analysis of systems. It is developed in the radar context and is devoted to the description of general targets exhibiting motion, scintillation and dispersivity. This description is based on a physical model of small independent reflectors which can be moving and non-permanent. The resulting representations are gener...
متن کاملA Comprehensive Approach to Develop a Continuous Fuzzy Guidance Law for Maneuvering Targets
Based on the idea of Continuous Fuzzy Guidance Law (CFGL), a andldquo;three-phase fuzzy guidanceandrdquo; (TFG) law is proposed for the class of surface to air homing missiles. The current approach enables the guidance law to track a maneuvering target from the beginning of the launch phase up to the terminal one while itdynamically attempts to keep miss-distance, flight time and control effort...
متن کاملIntegrated fuzzy guidance law for high maneuvering targets based on proportional navigation guidance
An integrated fuzzy guidance (IFG) law for a surface to air homing missile is introduced. The introduced approach is a modification of the well-known proportional navigation guidance (PNG) law. The IFG law enables the missile to approach a high maneuvering target while trying to minimize control effort as well as miss-distance in a two-stage flight. In the first stage, while the missile is far ...
متن کاملA Data Focusing method for Microwave Imaging of Extended Targets
This paper presents a data focusing method (DFM) to image extended targets using the multiple signal classification (MUSIC) algorithm. The restriction on the number of transmitter-receiver antennas in a microwave imaging system deteriorates profiling an extended target that comprises many point scatterers. Under such situation, the subspace-based linear inverse scattering methods, like the MUSI...
متن کاملA novel approach for the detection of maneuvering air targets in sea-clutter using High-Frequency Surface-Wave radar
A novel time-frequency signal decomposition approach is evaluated for the detection of maneuvering air targets in sea-clutter using High-Frequency Surface-Wave Radar (HFSWR). This approach is based upon time-frequency analysis and its eigenvalue decomposition. Results demonstrate that the new approach provides an effective way for detecting and analyzing maneuvering air targets in heavily clutt...
