7  Design Principles of Complex Algorithm Computational Process in Radar Systems

The exponential growth in digital technology since the 1980s, along with the corresponding decrease in its cost, has had a profound impact on the way radar systems are designed. More and more functions that were historically implemented in analog hardware are now being performed digitally, resulting in increased performance and flexibility and reduced size and cost. Advances in analog-to-digital converter (ADC) and digital-to-analog converter (DAC) technologies are pushing the border between analog and digital processing closer and closer to the antenna. For example, Figure 7.1 shows a simplified flowchart of the receiver front end of a typical radar system that ...
