We explain why search algorithms can find molecules with particular properties in an enormous chemical space (ca 1060 molecules) by considering only a tiny subset (typically 103−6 molecules). Using a very simple example, we show that the number of

Two‐dimensional (2‐D) transmit arrays offer many advantages over traditional over‐the‐horizon radar (OTHR) arrays, including the capability to steer and mitigate auroral clutter, a clutter type prevalent in polar operation, in all azimuth and

An antenna measurement drone was recently integrated by Defence Research and Development Canada to verify the performance of an over-the-horizon radar (OTHR) transmit array. This solution only uses off-the-shelf components and is very economical comp

Receive array design for Polar Over-the-Horizon Radar is driven primarily by the need to mitigate auroral radar clutter that appears at all azimuth angles. Arrays must be adequate to enable the detection and location of targets in the presence of thi

Two error types related to near-field measurements in over-the-horizon radar transmit beamformers are studied. The first concerns the use of measured array manifolds for beamformer calibration purposes and the second concerns performance verification

A MIMO radar approach is used in the lower portion of the frequency band of an over-the-horizon radar transmit beamformer to improve its robustness to calibration errors. By exploiting smaller Doppler frequency shifts at lower frequencies, the MIMO a

Robust beamforming is evaluated in an over-the-horizon radar that uses a planar array of monopoles in transmission. Significant auroral clutter rejection improvements are demonstrated with an appropriate choice of diagonal loading.

The use of planar arrays of monopoles is being considered by Defence Research and Development Canada for over-the-horizon radar to mitigate the impact of auroral clutter prevalent at northern latitudes. This is done by steering nulls towards the auro
