Title: **Mark B. Yeary: Innovating in Radar Technology and Signal Processing**

Introduction

Mark B. Yeary, an accomplished inventor based in Krum, TX, has made significant contributions to the fields of radar technology and signal processing. With three patents to his name, Yeary continues to push the boundaries of innovation, particularly in enhancing the capabilities of delta-sigma modulators and synthetic aperture radar imaging.

Latest Patents

One of Yeary's latest patents is the **Parameterizable Bandpass Delta-Sigma Modulator**. This invention features a first summation circuit that subtracts an error feedback signal from the input signal, incorporating a tunable signal transfer function. This function is crucial for setting a desired pole in the frequency response of the delta-sigma modulator (DSM). Additionally, it includes a second summation circuit for adding a noise transfer function to the output. The quantizer further refines this process by quantizing the output of the second summation circuit, allowing dynamic tuning of the center frequency and bandwidth of the DSM based on error feedback.

Another significant patent is for **Enhanced Radar Range Resolution**, which describes a synthetic aperture radar imaging method. This innovative approach combines radar return pulses with a sinusoid to shift the pulses to a baseband frequency while correcting for motion errors in the inertial navigation system measurements. The method effectively compresses each radar return pulse, generating enhanced resolution images. By convolving the return pulses with their corresponding transmission pulses, Yeary's invention improves range profile images and performs bandwidth extrapolation to eliminate grating lobes, leading to superior radar imagery.
