1. A radar system comprising:
a first receive channel including a first processing pipeline configured to generate a first beat signal, generate a first digitized beat signal from the first beat signal, compute a first range Fast Fourier (FFT) using the first digitized beat signal, and compute a first Doppler FFT using the first range FFT;
a second receive channel including a second processing pipeline configured to generate a second beat signal, generate a second digitized beat signal from the second beat signal, compute a second range FFT using the second digitized beat signal, and compute a second Doppler FFT using the second range FFT; and
a processing unit coupled to the first and second processing pipelines, the processing unit configured to compute a first angle FFT using the first Doppler FFT and compute a second angle FFT using the second Doppler FFT.
