Imaging radars that can see through clouds and weather are preferred sensors for Earth monitoring and target surveillance, but are traditionally large and heavy and carried by specialized and expensive satellite and aircraft platforms.
Now scientists at Singapore’s Nanyang Technological University (NTU) have developed a miniaturized radar system-on-chip that could enable all-weather synthetic-aperture-radar (SAR) imaging sensors to be carried by small unmanned aircraft.
Fitting on a fingertip, the microchip is an integrated Ku-band frequency-modulated continuous wave (FMCW) radar transceiver, including chirp generation, radio-frequency transmitter and receiver, dechirp processor and analog-to-digital converters.
