Utility
Calibrating array antennas based on signal energy distribution as a function of velocity
25 Jul 23
A radar antenna calibration method includes: forming a detection matrix from signals detected by an arrangement of receive antennas in response to chirps transmitted by an arrangement of transmit antennas, the detection matrix having multiple rows corresponding to the chirps, multiple columns corresponding to a signal sample, and multiple planes corresponding the receive antennas; deriving a range matrix by performing a frequency transform on a portion of each row of the detection matrix; extracting a slice of the range matrix, with different rows of the slice being associated with different chirps and with different receive antennas; deriving a velocity matrix from the extracted slice by performing a frequency transform on a portion of each column of the extracted slice; analyzing the velocity matrix to determine a current peak width; and adjusting, based on the current peak width, phase shifts associated with one or more of the receive antennas.

Utility
Envelope regulation in a frequency-modulated continuous-wave radar system
1 Nov 22
A radar system that can block false echoes includes: a local oscillator configured to generate a chirp signal comprising a plurality of chirps, each having a corresponding envelope; a transmitter configured to transmit a signal corresponding to the chirp signal; and a modulation circuit configured to modulate the transmitted signal by regulating a magnitude of one or more portions of the chirp envelopes in a predetermined pattern such that the radar system can discern false echoes which do not match the pattern.

Utility
Split-steer amplifier with invertible output
11 Oct 22
A split-steer amplifier with an invertible phase output, includes a first transistor having its base coupled to a positive node of an input port, its emitter coupled to ground, and collector connected to a positive intermediate node; a second transistor having its base coupled to a negative node of the input port, its emitter coupled to ground, and collector connected to a negative intermediate node; and multiple output ports each having a transistor arrangement operable to couple a positive node of that output port to the positive intermediate node and a negative node of that output port to the negative intermediate node, operable to couple the positive node of that output port to the negative intermediate node and the negative node of that output port to the positive intermediate node, and operable to decouple the positive node and the negative node of that output port from the intermediate nodes.
