1.2 Key System Specifications

Table 1-1 Key System Specifications
PARAMETER SPECIFICATIONS SHORT RANGE SPECIFICATIONS ULTRA-SHORT RANGE DETAILS
Maximum range 55 m 10 m This represents the maximum distance that the radar can detect an object, representing an RCS of approximately 10 m2.
Range resolution 0.43m 0.076m This is the ability of a radar system to distinguish between two or more targets on the same bearing, but at different ranges.
Maximum velocity 9.6 m/s 7.05 m/s This is the native maximum velocity obtained using a two-dimensional FFT on the frame data. This specification will be improved over time by showing how higher-level algorithms can extend the maximum measurable velocity beyond this limit.
Velocity resolution 0.149 m/s 0.1 m/s This parameter represents the capability of the radar sensor to distinguish between two or more objects at the same range, but moving with different velocities.
Please read the Section 2.4 in this reference guide to understand how to compute the values provided in the table.
