Abstract
Frequency modulated continuous wave (FMCW) radars have been widely used
for measuring target range and speed. In this paper, we present a mathematical
model that quantifies the system-level performance of FMCW radar systems.
In FMCW radar, the target range is measured through measuring the beat
frequency between the transmitted and received signal, usually by using Fast
Fourier Transform (FFT). One drawback of this approach is that when the beat
frequency of a target is not on the FFT grid, both the detection probability and
the false alarm rate (FAR) performances are degraded. In this paper, we propose
a new detector, using frequency shifts, that improves the detection probability
for off the grid targets at a cost of a slight increase in FAR.
