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 system for determining a position of a receiver from as few as two or three transmitters. The receiver may be stationary or moving with a known velocity. The system includes a receiver clock having a clock bias and a clock drift relative to a reference clock and may also include a motion sensor. A decoder receives transmitted signals from a number of transmitters and determine pseudo-ranges and transmitter frequencies therefrom and a processing unit receives the pseudo-ranges, the transmitter frequencies and the receiver velocity and determines the position of the receiver therefrom. When only two transmitters are available, the position of the receiver is determined dependent upon a known receiver clock drift. The system may also determine clock bias and, when three or more transmitters are available, receiver clock drift. The processing unit uses ranging and Doppler equations in combination, and may also use a measured velocity.

Abstract: A radar system including an AESA illuminates a target with a first pulse for a desired beam pointing angle (azimuth and elevation). The AESA then illuminates the target with a second pulse for the desired pointing angle, the second pulse defining a radiation pattern with a main beam in phase with the first pulse, but side lobes that are out of phase. The radar system receives return signals and combines the return signals to null the side lobes by the principle of superposition. The radar processing unit is time synced such that the pulse-pair is interpreted as a single ultra-low level side lobe return radiation pattern.

Abstract: Sensors coupled to a vehicle are calibrated, optionally using a dynamic scene with sensor targets around a motorized turntable that rotates the vehicle to different orientations. One vehicle sensor captures a representation of one feature of a sensor target, while another vehicle sensor captures a representation of a different feature of the sensor target, the two features of the sensor target having known relative positioning on the target. The vehicle generates a transformation that maps the captured representations of the two features to positions around the vehicle based on the known relative positioning of the two features on the target.

Abstract: This document describes an object tracker that performs stable velocity initialization for radar tracks, using multiple hypotheses, including when only sparse radar point clouds are available. With just a single point per scan, the tracker creates multiple hypotheses for the direction and speed of an object. A least square function can be applied to each hypothesis to derive each respective initial velocity, which are tracked using a Kalman Filter during a hypotheses tracking period. When hypotheses are initialized and tracked on each hypothesis tracking period, their track error scores are computed. Based on their track error scores, the hypotheses that have low evidence are discarded during the hypotheses tracking period. When the hypotheses tracking period ends, a hypothesis with high evidence initializes the track's velocity. Parallel hypothesis evaluation enables the tracker to initialize a velocity quickly and accurately by merely selecting the best hypothesis, which may enable safer driving.
