Abstract: Detection of a radar target from a received radar signal includes computing a vector of filter weights dependent upon a steering vector and determining a threshold value dependent upon a designated probability of false alarm. The vector of filter weights is applied to samples of the received radar signal at a test cell, corresponding to a test range, to provide a filtered test signal and a test power of the filtered test signal is computed. The weights are also applied to samples of the received radar signal at a number of reference cells, to produce filtered reference signals. A reference power is computed from the filtered reference signals and the radar target is detected at the test range when a ratio of the test power to the reference power exceeds the threshold value.

Abstract: The present invention relates to radar systems and methods of using same that are more efficient than current radar systems and methods of using same. Such radar systems and methods of using same using employs a plurality of pluses is used to make a decision on the presence or absence of a target. Such radar system and method of using same is more efficient as the position and velocity of a potential target is carried over from pulse burst to pulse burst. Thus, the radar signal structure from the target is the same, which in turn results in a high cross correlation that can used to efficiently decide if signal return is from an actual target or is due to interference.

Abstract: A radar system provides a transmitter that transmits a sequence of transmitted pulses in a transmit beam, receiving antenna array comprised of more than one element, and a receiver communicatively coupled to the receiving antenna area to receive received signal that comprises in-phase and quadrature samples collected of a reflected version of the sequence of transmitted pulses. A signal processing and target detection module resolves a received signal-plus-interference into different range cells based on a time delay between the transmitted pulse and the received signal, wherein a response from a range cell to a transmitted pulse is due to a target within the transmit beam and moving at an unknown velocity. An interference suppression module suppresses interference and test for presence of a target tested at each of a set of hypothesized azimuth angles and Doppler frequencies.
