A Millimetre Wave Radar Sensor for Autonomous Navigation and Landing

Vehicles, houses, small buildings 2-3m but in the longer term, residual errors and biases integrate up into unacceptably large position errors. Under these conditions, millimetre wave radar can be applied in a number of ways to improve the navigation accuracy. It can be used as a Doppler sensor to improve the velocity estimation accuracy by measuring the ground speed, or it can be used to produce high resolution images that can either be matched autonomously to features in the region for navigation purposes or to offer a pilot an image of the runway to aid with landing.
