摘要： Methods, apparatus, and computer program products are provided for improving the crossrange resolution of a radar device for more accurate determinations of angular position of a target. The radar device transmits and receives scanning signals at crossrange beam positions having a beamwidth, wherein the beam positions are separated by a step. The radar device scans a target to receive target data from at least three beam positions, typically consecutive beam positions, to determine a first beam position with a first target data value that is greater than a second target data value of a second beam position preceding the first beam position and greater than a third target data value of a third beam position following the first beam position. A target data relationship between the first, second, and third beam positions is determined to provide the angular position of the target relative to the first beam position.

摘要： A pulse radar system including an RF exciter for generating a repeating sequence of internal pulses of RF energy of different frequencies. A transmit circuit responsive to the internal pulses of RF energy generates a transmit radar signal comprising a transmit repeating sequence of transmit intervals during which pulses of RF energy are transmitted. A single receiver responsive to the repeating sequence of internal RF pulses receives radar return signals based on all of the RF frequencies in a receive repeating sequence of receive intervals which do not occur at the same time as said transmit intervals.
