1.3 Key System Specification

This reference design is based on the mmWave demo (mmwave_demo) processing chain from the mmWave low-power software development kit (MMWAVE-L-SDK). The reference design demo uses a BPM-MIMO scheme and contains additional features such as radar cube compression, maximum velocity extension, dynamic clutter removal, and a group tracker.

Table 1-1 Key System Specification
PARAMETERSPECIFICATIONSDETAILS
Maximum range (m)

120

This is the maximum range supported by the chirp configuration shown in Table 2-1. The maximum detectable range for a given object depends on the Radar cross section (RCS) of the object
Range resolution (m)

0.94

This is the minimum range difference over which two individual point targets can be distinguished by the chirp configuration shown in Table 2-1. The theoretical achievable resolution by AWRL1432 is 3.75cm based on 4GHz bandwidth.
Maximum velocity (kmph)±144This is the extended maximum velocity obtained using the Chinese Remainder Theorem on alternating frames.
Velocity resolution (kmph)

1.13

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.
Azimuth angular resolution (Deg) 20This is the native azimuth angular resolution based on the virtual array aperture
