摘要： A radar system is provided in accordance with various embodiments herein. The radar system includes a transceiver, an analog to digital converter (ADC), a digital processing unit coupled to the ADC, a control unit coupled to the digital processing unit, and a twiddle factor table. The digital processing unit includes a plurality of fast Fourier transform (FFT) elements and a plurality of memory storage devices coupled to the plurality of FFT elements. The plurality of FFT elements and the plurality of memory storage devices are configured in a pipeline. The control unit is configured to control each of the plurality of FFT elements a predetermined number of times. Each twiddle factor in the twiddle factor table corresponds to an FFT element in the plurality of FFT elements. A pipelined Fast Fourier Transform (FFT) sequence of radix-4 elements is configured in stages and can be operated iteratively.

摘要： Examples disclosed herein relate to a switched coupled inductance phase shift mechanism. The phase shift mechanism includes a variable inductor element configured to toggle between a first inductance state and a second inductance state in response to a first control bit value, and a plurality of variable capacitor elements coupled to the variable inductor element and configured to toggle between a first capacitance state and a second capacitance state in response to a second control bit value. The variable inductor element and the variable capacitor elements collectively produce a first phase shift using the first inductance and capacitance states, and collectively produce a second phase shift using the second inductance and capacitance states, where a target phase shift is produced from a difference between the first and second phase shifts. Other examples disclosed herein relate to an antenna array and a method of phase shifting with switched coupled inductance.
