An introduction to the theory of sliding window detection processes, used as alternatives to optimal Neyman-Pearson based radar detectors, is presented. Included is an outline of their historical development, together with an explanation for the resurgence of interest in such detectors for operation in modern maritime surveillance radar clutter. In particular, recent research has developed crit...

in this paper, we deal with the problem of adaptive coherent signal detection in gaussian interference (clutter plus noise) for surveillance pulse radars. some of the adaptive radar detectors exploit the ar model for clutter. most of these detectors have been obtained using the glr test. this test relies on the maximum likelihood estimation whose accuracy depends on the number of data. whereas,...

A reliable and effective hybrid beamforming design for dual functioning multi-input multi-output (MIMO) radar is a challenging research problem because of the concerns related to limited user capacity, interference, lack performance trade-off. Due shortage available spectrum, frequency spectrum sharing has become vital in emerging 5G communication systems. This will reduce congestion, therefore...

Over the last decade of the 20th century, the emerging ultrawide-band (UWB) impulse technology has found numerous applications in the commercial as well as the military sectors. The rapid technological advances have made it possible to implement (cost-effective, short-range) impulse radar and impulse-radio communication and localization systems. Array beamforming and space–time processing techn...

Various interference sources either intentional or unintentional can mask the synthetic aperture radar (SAR) signals and cause image degradation. With a novel data acquisition mode, a new method based on dual-channel SAR is applied to suppress the interference. Using the received dual-channel data, the two-dimensional location of the interference source can be estimated and then the interferenc...

With the development of wireless communication technology, electromagnetic interference (EMI) artificial radio to weather radar increases significantly, which has a serious impact on quality data. Most research detecting and suppressing was based primary product radar. This paper researches effectiveness deep convolutional neural networks (DCNN) identify suppress I/Q data output from front end ...

We focus on a dual-functional multi-input-multioutput (MIMO) radar-communication (RadCom) system, where a single transmitter communicates with downlink cellular users and detects radar targets simultaneously. Several design criteria are considered for minimizing the downlink multi-user interference. First, we consider both the omnidirectional and directional beampattern design problems, where t...

Multiple-input multiple-output (MIMO) radar has superior performance to conventional one. It has been introduced to almost every application field of conventional radar in recent years. In practical application, MIMO radar also faces the problem of congested spectrum assignment, which makes it not possible to have a continuous clear band with large bandwidth. Sparse frequency waveform that cont...

For meters of angular coordinates pulse-Doppler tracking radar escort that implement the method amplitude instantaneous comparison radio signals, a methodology for synthesis algorithm diversion combined imitating and masking jamming (CIM) has been developed. The calculation comparative analysis errors evaluating air target CIM-jamming when choosing as sources veil information: retaliatory noise...
