Publication number: 20160216367Abstract: Various implementations described herein are directed to frequency correction for pulse compression radar. In one implementation, a method may include generating a first transmission signal using a pulse compression radar system based on an ideal waveform signal. The method may also include measuring a frequency of the first transmission signal at an output of a transmitter module. The method may further include comparing the measured frequency of the first transmission signal and a frequency of the ideal waveform signal. The method may additionally include generating pre-distortion coefficients based on the comparison, where the pre-distortion coefficients are configured to compensate for a difference between the measured frequency of the first transmission signal and the frequency of the ideal waveform signal. In addition, the method may include generating a compensated transmission signal using the pulse compression radar system based on the pre-distortion coefficients and the ideal waveform signal.Type: ApplicationFiled: January 22, 2016Publication date: July 28, 2016Inventors: Roger Phillips, Graeme Bell, Gregor Storz, Lindsay Lilburn

Publication number: 20160216368Abstract: Various implementations described herein are directed to adaptive frequency correction for pulse compression radar. In one implementation, a method may include generating a first transmission signal using a first direct digital synthesizer of a pulse compression radar system based on frequency sweep coefficients. The method may also include comparing a frequency of the first transmission signal at a feedback loop of a phase locked loop circuit and a frequency of an ideal waveform signal. The method may further include generating adaptive frequency coefficients based on the comparison, where the adaptive frequency coefficients are configured to compensate for a difference between the frequency of the first transmission signal at the feedback loop and the frequency of the ideal waveform signal. The method may additionally include generating a compensated transmission signal using the pulse compression radar system based on the adaptive frequency coefficients and the frequency sweep coefficients.Type: ApplicationFiled: January 22, 2016Publication date: July 28, 2016Inventors: Roger Phillips, Andrew Corbett, Graeme Auckland, Gregor Storz, Lindsay Lilburn
