Time-domain back-projection (BP) is a widely known method used in synthetic aperture radar (SAR) image formation. Despite its advantages over other image formation algorithms, the BP method is hindered due to its computational complexity and its requ

Conventionally, the Fast Fourier Transform (FFT) has been adopted over the Discrete Fourier Transform (DFT) due to its faster execution. However, the emergence of modern high performance computing devices has favored the DFT algorithm due to its inhe

Historically, FPGA designers have used integer processing whenever possible because floating-point processing was prohibitively costly due to higher logic requirements and speed reduction. Therefore, fixed-point processing was the norm. Recently, Int

Detecting changes in an uncontrolled environment using cameras mounted on a ground vehicle is critical for the detection of roadside Improvised Explosive Devices (IEDs). Hidden IEDs are often accompanied by visible markers, whose appearances are a pr

Frequency-domain algorithms are used frequently to form Synthetic Aperture Radar (SAR) images from SAR video phase histories (VPH). Even though frequency-domain algorithms are computationally efficient, they work under many assumptions that do not ho
