摘要： A chip-implementation of a millimeter wave MIMO radar comprises transmitters for transmitting short bursts of digitally modulated radar carrier signals and receivers for receiving delayed echoes of those signals. Various signal formats defined by the number of bits per transmit burst, the transmit burst duration, the receive period duration, the bitrate, the number of range bins, and the number of bursts per scan, facilitate the choice of modulating bit patterns such that when correlating for target echoes over an entire scan, the correlation codes for different ranges and different transmitters are mutually orthogonal or nearly so as compared to a random selection of codes. In the event of imperfect orthogonality, the subtraction of strong already-detected target signals allows for better detecting of weaker signals or moving targets that are rendered non-orthogonal by their Doppler shift.

摘要： A retrofit system applied to existing FMCW radars in order to convert them into pulsed linear frequency-modulated radars with the ability to dynamically switch between two pulsed modes and an FMCW mode based on the estimated range of a target. This retrofit also includes provisions for adaptively configuring chirp and sweep parameters to optimize range resolution. The result is a retrofit system capable of converting an FMCW radar into a dual pulsed mode radar with adaptive sweep configuration.

In various embodiments, the apparatus comprises a field transceiver module and a computing node in communication with each other. The field transceiver module is configured to generate an electromagnetic probe carrier field; under the control of the computing node, phase-modulate the carrier probe field according to a time-periodic probe modulation waveform having a probe modulation phase that includes a probe modulation frequency and a probe modulation phase offset, thereby generating a modulated probe field; direct the modulated probe field at one or more targets and to receive a modulated reflected probe field from one or more targets; demodulate the modulated reflected probe field and generate a probe signal corresponding to the probe modulation waveform. The computing node is configured to generate a control signal corresponding to the probe modulation waveform; receive the probe signal from the field transceiver module; compute a product of the probe signal and a time periodic reference waveform having a reference phase that includes a reference frequency and a reference phase offset; compute an amplitude or a power of the product; determine one or more reference waveforms corresponding to extrema of the amplitude or the power of the product; and determine the range to the one or more targets based on the extrema of the amplitude or the power of the product.

摘要： A method of tracking objects using a radar, includes sending a beamcode to at least one radar antenna to set a predetermined direction, using samples from a random distribution of at least one of a phase or an amplitude to generate a tracking signal pulse train, transmitting the pulse train from the at least one antenna within a pulse time window, receiving return signals from objects at the at least one antenna, and using the return signals to gather data to track the objects. A radar system has at least one radar antenna to transmit a tracking signal, a memory to store a set of random distributions, a controller connected to at least one radar antenna and the memory, the controller to execute instructions to determine which random distribution to use, generate a pulse train using the random distribution, transmit the pulse train to the at least one radar antenna as the tracking signal, and gather measurement data about objects returning signals from the tracking signal.
