HFSS RCS Backscatter

Below is an RCS backscatter simulation of a cylinder up to 100 GHz. The main goal of this task was to gain a comfort level using HFSS to perform further RCS backscatter simulations in the future. Using HFSS has been interesting, especially due to the amount of computing strength it may require at times. I look forward to using this program more in the future.

Attached is also a PDF guide (not my own) that can be useful for performing a similar simulation: Getting_Started_with_HFSS

MATLAB Data Analysis


The following code was one component of my current Senior Design Project assignment, which will involve the creation of a device known as the “Audio Awareness Enabler.” More information relating to this project is sure to follow in the future. For now, let us take a look at the following MATLAB code, which takes excel files of data and calculates the averages and standard deviations and then plots a Gaussian normal plot. Soon, this code will be modified to be able to determine whether a set of data will fall into the “ambient” range or one of the three interrupt levels. It will also eventually seek to create a formula that will determine whether a set of data is in the interrupt zone based on the ambient level.

ADS Coupler Momentum Simulation

Build the ADS circuit.


Run the momentum simulation and set parameters such as substrate.


This is a momentum simulation. Let’s see if we can optimize this.


Export the part to be used as a component in the workspace library in ADS.


Now run an ADS simulation using the exported component, which uses a database of simulated results.


If you step into the component, you will see component features.


Now, tune the parameters to begin optimization.


I-Q Demodulation for Radar Cross Section Measurements

RCS/ISAR Data Acquisition


Of critical importance to attaining an RCS measurement is the doppler shift, a change in return frequency that results in the movement of an object. I-Q demodulation is useful for attaining this measurement, producing the difference as an output signal when supplied two signals of different frequencies. The following MATLAB program utilizes a set of data acquired using an oscilloscope to test a demodulator. This is part of a project being undertaken at the UMASS Dartmouth RF/Photonics Lab.
