ABSTRACT
<p>Based on frequency-domain system-identification techniques combined with an optimal model-order selection, this modeling method efficiently simulates microwave radiometers. A broadband microwave receiver (with astronomical applications) is modeled and simulated to illustrate the technique. This particular receiver is a challenging case because it samples cosmic microwave background (CMB) low-power broadband (10-gigahertz) signals over a long period.</p>
