This paper addresses a novel SAR imaging scheme based on 1-bit sampling assisted with a
single-frequency threshold. The 1-bit sampling approach is able to considerably reduce the …

In order to achieve a high range resolution and low instantaneous bandwidth, stepped
frequency synthetic aperture radar (SAR) is widely used with stepped-frequency chirps and …

Future spaceborne synthetic aperture radar (SAR) systems will be required to produce high-
resolution imagery over a wide area of surveillance. However, the minimum antenna area …

Stepped-frequency waveforms can achieve an ultrawide bandwidth by using a sequence of
single-frequency pulses. The advantages of stepped-frequency waveforms are low …

Since the width of range swath of synthetic aperture radar (SAR) is restricted by the pulse
repetition frequency, there exists a tradeoff between the azimuth resolution and the range …

One-bit synthetic aperture radar (SAR) imaging has garnered significant interest due to its
ability to lower the cost of storing enormous amounts of data during sampling and …

Conventional synthetic aperture radar (SAR) systems are limited in their ability to satisfy the
increasing requirement for improved spatial resolution and wider coverage. The demand for …

It has been proven that the imaging quality of 1-bit quantized synthetic aperture radar (SAR)
data can be improved by using an imaging scheme of a single-frequency threshold (SFT). In …

A new method for processing multichannel synthetic aperture radar (SAR) data to achieve
desirable image characteristics is presented. The method is optimal because it is derived by …

A new modeling method for representing distributed scattering centers in wide-angle
synthetic aperture radar (SAR) is presented. The proposed multipeak model approximates …
