abstract according to the adventages of passive radars they have been reconsidered recently due to development of signal processing technology. in the field of sea targets detection using passive radar few research have been reported. this paper presents a new method to detect sea targets using adaptive filter weights variation model and using the fact that the radar cross section of sea target...

Introduction: Mars Express (MEX) bistatic radar (BSR) ground tracks will not move to far northern (e.g., Phoenix) latitudes until June 2006. But the generally uniform appearance of these plains areas suggests that certain surface characteristics may be inferred from observations already in hand. Of particular interest are two MEX experiments conducted in the vicinity of the Viking Lander 2 site...

The Chebyshev approximation technique (CAT) combined with the MoM based on electric-field integral equation (EFIE) and Poggio–Miller–Chang–Harrington–Wu–Tsai (PMCHWT) is proposed to efficiently calculate wide-band radar cross-section (RCS) passive bistatic radars (PBR). EFIE-PMCHWT equations can be used analyze electromagnetic scattering of coated targets. combination CAT only requires computin...

A theoretical model that describes the power of a scattered Global Positioning System (GPS) signal as a function of geometrical and environmental parameters has been developed. This model is based on a bistatic radar equation derived using the geometric optics limit of the Kirchhoff approximation. The waveform (i.e., the time-delayed power obtained in the delay-mapping technique) depends on a w...

Synthetic Aperture Radar is well known for producing a radar image of the ground, so it can be used for detecting onthe-ground object which is interesting for some applications. A possible application can be Foreign Object Detection (FOD), which is an important issue in aviation safety. A ground-based Circular Bistatic Synthetic Aperture Radar (Circular-BiSAR) is introduced in this paper. The c...

The second Radio Aurora Explorer satellite, RAX-2, is a triple CubeSat studying the formation of plasma irregularities in Earth’s ionosphere. The spacecraft was developed jointly by SRI International and the University of Michigan, and it is the first satellite funded by the National Science Foundation. RAX-2 launched October 28, 2011 and is currently operating on orbit. RAX uses a bistatic rad...

This article examines methods for and results of determining the instantaneous kinematic state a target, i.e., its velocity heading, using passive multistatic radar. is achieved by combining bistatic target range Doppler information obtained multiple transmitter-receiver pairs, to estimate appropriate vector. estimation provided as set closed-form equations, derived general case applicable an a...
