IEEE EMCS & AESS Technical Meeting
The Huntsville Chapters of the IEEE Electromagnetic Compatibility (EMC) Society and the Aerospace Electronics and Systems Society (AESS) invites you to attend a joint Technical Meeting on September 26, 2019 featuring a talk given by John Spitzmiller of Parsons. The program will begin at 5:30 pm with David Hall of SMA sponsoring a free catered meal. Mr. Spitzmiller’s technical presentation will begin at approximately 6:20 pm after some short chapter status updates.
”The Stretch Processor’s Response to Monochromatic Interference”
Synopsis: Stretch processing, a popular pulse-compression method for modern radars using wideband linear frequency modulation, efficiently achieves fine range resolution for accurate range measurement, target discrimination, and high-resolution imaging. However, additive interference signals, both random and deterministic, degrade the stretch processor’s performance. One such interference signal potentially encountered in real-world RF-interference environments is a deterministic monochromatic signal (pure sinusoid). This presentation offers two approaches to characterizing the stretch processor’s response to monochromatic interference.
We first review the fundamental mathematics of stretch processing. Then, using a rigorous application of traditional signal-processing theory and methods, we derive the solution to the stretch processor’s exact response to monochromatic interference. To verify the derived solution’s correctness, we present digitally simulated stretch-processor outputs which agree with the derived solution’s predictions.
We next innovatively apply the principle of stationary phase to derive a more mathematically convenient yet highly accurate approximation to the stretch processor’s response to monochromatic interference. Favorable agreement of the derived approximation’s predictions with the corresponding exact solution for several example cases verifies the approximation’s accuracy.
The meeting will be held at ADTRAN in the East Tower, 2nd Floor, FountainView Conference Room. The directions are included below (follow the Blue line on the map).
The meal and presentation are open to anyone interested in EMC: IEEE membership is not required to attend. Seating is limited to the first 75 people registered. Please RSVP/Register below.
