A true time delay beamforming system and calibration method for transmission and reception of a beam is disclosed. The true time delay beamforming system comprises at least one input signal received by at least one signal conditioning device, wherein the signal conditioning device is adapted to provide selective, independent, and variable control of one of a phase delay, a time delay and an amplitude of the input signal to produce an output signal. A control logic device is adapted to provide a control logic signal to the at least one signal conditioning device for selectively activating and controlling the signal conditioning device. The true time delay beamforming system may further include an automatic calibration system that generates an error correction signal based on errors detected in the output signal, and selectively adjusts the control logic signal based thereon.
