    Based on the space-time two dimensional signal processing, this paper proposes a new method for the imaging of moving targets with SAR by using the equivalent space-time echoes of an array antenna. This method, which is much more effective for detecting and imaging targets whose radial velocity is very much smaller than a single antenna, has no blind area of velocity and can provide a high-resolut...

    This paper describes a new algorithm for implementing wide angle imaging. The new algorithm is derived from the enhanced image processing (EIP) algorithm described by Ausherman et al. (1984) and is based on using the Fast Fourier Transform (FFT) to rotate and interpolate the linear images before compositing. The new algorithm is more accurate than the linear interpolation based compositing scheme ... View full abstract»

    An alternative to using a phased array to steer a high frequency microwave beam is to electronically control the orientation of an inertialess broadband microwave reflector. Such a system could steer one or more high power beams for search or tracking radars, and the system could possess wide instantaneous bandwidth. Experiments have demonstrated that a planar plasma mirror can be formed with elec... View full abstract»

    The goal of neural beamforming is to design neural processing algorithms which adapt to low cost phased array antennas, even when they behave non-linearly, are imperfectly manufactured, or become degraded. Neural beamforming techniques have the potential to decrease antenna manufacturing and maintenance costs, while increasing mission time and performance before repair. The authors introduce a neu...
