Abstract
Due to the characteristics of light weight, low cost, and high resolution, millimeter wave (MMW) multiple-input multiple-output (MIMO) radars are widely applied in remote sensing and automotive systems. The MMW MIMO radar orthogonal waveform design is a key issue based on dechirp-on-receive technique to acquire high degree of freedom (DOF). In this paper, we propose an optimized interleaved orthogonal frequency division multiplexing (I-OFDM) chirp waveform design scheme using unequal sub-chirp duration and sparse sub-band constraint to further reduce the mutual interference (MI) between waveforms, and analyze the orthogonality of the original and optimized I-OFDM chirp waveform for MMW MIMO radar based on dechirp processing from various aspects. The simulation results show the effectiveness of the proposed method.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
