چکیده

We present a flexible time-domain synthetic aperture radar signal simulation system. We demonstrate its use in simulating clutter, stationary and moving targets. The point target analysis shows that the observed impulse response agrees with theoretical values. Clutter results how that the observed clutter corresponds to K distribution model. We also demonstrate that the system may be used for the simulation and analysis of ground moving target indication (GMTI) systems.

Modeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO

The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

Improving adaptive resolution of analog to digital converters using least squares mean method

This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...

A Hybrid Multichannel Processing Method for Spaceborne Hybrid Phased-MIMO SAR with Application to Multi-Direction Swath Imaging

This paper proposes a hybrid multichannel processing method for spaceborne Hybrid Phased-MIMO SAR (HPMSAR) that can achieve different applications of multi-direction swath imaging on the same platform. The method is optimal because it is a combination of two-dimension (2D) advanced digital beamforming (DBF) technology and multichannel pre-filter technology for highresolution wide-swath SAR sign...

Signal Identification Using a New High Efficient Technique

Automatic signal type identification (ASTI) is an important topic for both the civilian and military domains. Most of the proposed identifiers can only recognize a few types of digital signal and usually need high levels of SNRs. This paper presents a new high efficient technique that includes a variety of digital signal types. In this technique, a combination of higher order moments and hi...
