Abstract
The purpose of this paper is to introduce and evaluate a number of techniques to prevent a radar being used by an adversary as a bistatic illuminator of opportunity. These are all based on the idea of radiating a so-called "masking signal" which is arranged to be orthogonal, both in a spatial sense and in a coding sense, to the radar signal, and of a level sufficient to mask the radar signal to an adversary, and hence to deny a reference for bistatic operation. The overall performance of the scheme is quantified in terms of two parameters: (i) the degree of masking of the radar signal by the masking signal, and (ii) the degree of suppression of echoes (from targets or from clutter) of the masking signal in the channels of the radar receiver. The choice of waveforms is considered, followed by a description of two approaches to the choice of radiation patterns, and then the results of some simulations of the overall performance are presented.

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
