Abstract
A transmit system for collision avoidance systems having autocalibration. A four element antenna array is provided. Each element is selectively connectable to a transmitter through a power divider and a isolator. Three of the elements further have a programmable phase shifter in line to the transmitter. A phase detector having a first input selectably connectable to one of the elements and a second output connected to the transmitter is provided. By selectively connecting one element to the transmitter and one element to the phase detector and then selectively programming the appropriate phase shifters, the differentiated phase delay in each channel of components associated with an antenna element can be calibrated.
