Radar tomography using MIMO noise radar and antenna with beam synthesis

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
Conventional SAR generates 2D image using combination of range compression and 1D aperture synthesis. The range resolution of such approach is determined by the signal spectrum width, while cross-range resolution is defined by the synthetic aperture length.

Acoustooptic Correlation Processing in Random Noise Radar

IEEE Geoscience and Remote Sensing Letters, 2004
A new technique has been developed that permits coherent processing of backscatter data acquired by a radar system transmitting ultrawideband (UWB) random noise waveforms and processing the received signals using a heterodyne correlation receiver.

Noise-correlating radar based on retrodirective antennas

IEEE Transactions on Aerospace and Electronic Systems, 2007
A new retrodirective antenna-based search radar system has been introduced. The suggested system uses a noise correlation technique to detect the presence and the direction of the target. Simulation and analytical results show an order of magnitude improvement in acquisition time of the radar when compared with a phased array antenna-based radar system

Chaos Generators for Noise Radar

2009
We present results of top-down design of chaos generators that are based on nonlinear electronic systems. Several types of chaotic waveform generators are described such as Weak Resonant BWO, multi-mode resonant systems, time-delayed circuits of ring and reflection feedback types, etc.

Noise in radar and intercept systems

2018
Noise of all kinds limits ultimate detection performance for all electromagnetic sensor systems whether cosmic, UV, visible, IR, microwave or RF. Thermal noise is often thought of as the ultimate limitation on detection and tracking but often it is self-noise in a sensor system, which limits performance.

Monopulse-radar angle tracking in noise or noise jamming

IEEE Transactions on Aerospace and Electronic Systems, 1992
In many monopulse radars, feedback in the angle-tracking servo system is taken to be directly proportional to the monopulse ratio. In those radars, monopulse measurements are conditioned on simultaneous occurrences of receiver sum-channel video exceeding a detection threshold: if a detection fails to occur, the measurement is ignored, and the angle ...
