Abstract: A data code generator produces a data code, while a reference code generator produces a reference code. The data code is phase-shifted by the data code generator in a predetermined sweep range, according to a sweep command signal given by a phase difference detector. The phase difference detector compares the phase of the data code with that of the reference code to obtain phase difference data. Based on the phase difference data, a correction signal generator produces a correction signal to keep the data code in phase with the reference, code. The phase setter optimizes the phase of the data code according to the correction signal.

Abstract: A radar that detects whether spike noise due to an interference with a transmission signal from an object vehicle is superimposed on a beat signal obtained from the transmission signal and a reception signal. When the spike noise is detected, a threshold for extracting a peak from a frequency spectrum is temporarily increased. Normally, a threshold (TH0) is set not so as to extract background noise as a target peak. When the spike noise is detected, a noise floor level (NFL) of the frequency spectrum is determined on the basis of the maximum absolute value of the spike noise, and a threshold (TH1) higher by a predetermined amount ?L than the threshold TH0 is set. This allows a proper target peak to be accurately extracted without mistakenly extracting many peaks caused by the noise as the target peaks.

Abstract: Detection of failure mode peculiar to a high-electron mobility transistor is available. A control circuit controls a gate voltage switching portion so that the gate voltage applied to a transistor may become a given checking voltage. The checking voltage may be set to a pinch-off-voltage of the transistor, for example. The control circuit detects a current value of the drain current flown when the checking voltage is applied, thereby detecting a failure of the transistor based on the current value. According to the present invention, since failure detection is made on the basis of the drain current value flown when the checking voltage set up apart from an operating voltage is applied as the gate voltage, failure mode which is peculiar to the high electron mobility transistor and which is hardly detectable in an ordinary operating state becomes detectable.

Abstract: Provided herein are systems and methods for achieving long coherent integration in a navigational receiver to improve the sensitivity of the receiver and enable the receiver to acquire, reacquire and track signals under very weak signal conditions. In an embodiment, phase compensation is computed based on estimated Doppler frequency, rate of change of the Doppler frequency with time, and second order rate of change of the Doppler frequency. The Doppler frequency may be computed from an orbital model or ephemeris. This phase compensation is used to compensate samples of the input signal for changes in the phase due to the Doppler frequency. Frequency components of the phase-compensated samples are then computed using a frequency analysis such as a Fast Fourier Transform (FFT). The maximum frequency component is taken as an error frequency and used to compensate the samples of the input signal for residual frequency error.
