Radio Wave Reradiation/Reflection TRIZ Cases

Phase normalization compensates carrier frequency shifts in beat signals, improving AoA and range estimation for clearer radar image maps.

Weighted object tracking and heading-angle estimation correct a target vehicle's transverse position during lane changes for steadier ADAS control.

A braced SAR corner reflector with survey pins and GNSS monitoring maintains sub-centimeter position stability for long-term satellite calibration.

Backscatter arrays within one SAR resolution cell replace large corner reflectors and feed known parameters into image calibration.

Time-of-flight sensing maps overhead and side obstructions so control circuitry can calculate usable vehicle clearance and guide safer maneuvers.

A separate pivoting arm below the outside mirror lets the rear sensor avoid equipment blockage and detect low-height objects more effectively.

Varying FMCW chirp start and stop frequencies with DDM phase coding separates concurrent MIMO transmit channels and improves range resolution.

Baseband signal processing estimates radar and GNSS antenna phase centers in situ, avoiding feed-port access and preserving system integrity.

Varying chirp density across MIMO radar antennas expands velocity range to SIMO level while reducing velocity aliasing and preserving angular resolution.

Passive radar reflectors let a following vehicle track a lead vehicle and hold constant spacing in agricultural fields without lane markings.

Space-time block codes give MIMO radar transmitters orthogonality, cancelling cross-correlation noise and improving moving target detection.
