ABSTRACT
The Novelda Nanoscale Impulse Radar illustrates some technically advanced principles of ultrawideband (UWB) impulse radar design. Figure 11.1a shows the 5-× 5-mm package for the 2-× 2-mm complementary metal-oxide-semiconductor (CMOS) chip containing all of the essential radar subsystems [1,5]. The chip works with the radar assembly shown in Figure 11.1b, which includes a circuit board with antennas and serial peripheral interface (SPI) connections for digital computer control. The Novelda radar is a general-purpose radar that the user can program and conŽgure for sensing applications at ranges up to 60 m with 4-mm spatial resolution. The system architecture has several unique processing features including the continuous time binary valued (CTBV) design paradigm. You will see the basic principles of the Novelda radar in many of the radars described in this book.
