Technology for future mobile ground surveillance radars
Abstract
Radar systems that are usually active (that is, monostatic radar in which the transmitter and receiver are housed in the same unit) operate through electromagnetic emission. As a consequence, special precautions must be taken to make the radar more secure against interception and spoofing and less vulnerable to electronic countermeasures. One method of increasing security is the use of spread spectrum techniques, for example, binary phase modulation of the transmitter, which produces pseudo-noise-encoded phase-shift keying of the transmit frequency. More rapid and elaborate signal and data processing, including higher Doppler resolution for better tracking and clutter rejection, together with more refined tracking algorithms to prevent track breaking by crossing targets, are additional protective measures that can improve performance. It is thought that in the future very high speed integrated circuits will significanly influence radar systems and increase their versatility.
