1. A system for blindzone obstacle detection for a host vehicle, wherein the system comprises: a sensor array configured to generate measurement data for a blindzone of the host vehicle; a blindzone object detector comprising at least two detectors that each employ a different detection technique, the blindzone object detector being coupled to the sensor array to receive the measurement data, to process the measurement data using at least two separate detection techniques to produce at least two detection outputs and to combine the at least two detection outputs using a fusion detection technique to form a final detection value used to detect an object in the blindzone of the host vehicle; and an indicator coupled to the blindzone object detector and being configured to generate an indication of object detection in the blindzone, wherein the at least two separate detection techniques comprise at least two of a frequency-based detection technique, a time-based detection technique and an image-based detection technique, wherein the frequency-based detection technique comprises a frequency-based analysis of the measurement data, the time-based detection technique comprises a time-based analysis of the measurement data and the image-based detection technique comprises an image-based analysis of the measurement data using image processing techniques.
