摘要： PROBLEM TO BE SOLVED: To provide more accurate Doppler velocity observation data in a meteorological radar device by integrating two typical Doppler velocity calculation methods, a FFT method and a PPP method, which have mutually incompatible properties.SOLUTION: A meteorological radar device: simultaneously calculates Doppler velocities and velocity widths by both a FFT method and a PPP method; compares the Doppler velocities calculated by the both methods with a threshold; when the both Doppler velocities are larger than the threshold, adopts the Doppler velocity calculated by the PPP method which does not have degradation of a frequency resolution due to an effect of a finite term truncation error; when either one of the two Doppler velocities calculated by the both methods is smaller than the threshold, outputs the Doppler velocity calculated by the method which gives smaller value for the velocity width. Thus, by calculating in this way, the meteorological radar device can provide more accurate Doppler velocity observation data.

摘要： PROBLEM TO BE SOLVED: To solve the problem wherein, though a method for adding a lamp characteristic to the head and the terminal of a transmission pulse to aim time side lobe suppression is proposed, in a radar device wherein the transmission pulse to which optional frequency modulation is applied in a pulse width is emitted into a space and a reflected wave from a target is received and subjected to pulse compression processing, frequency sweep is continued even during a transition period of the added lamp characteristic in the method, and thereby an effective band in the transmission pulse is damaged, and a compression pulse width is expanded, namely, a distance resolution is deteriorated.
SOLUTION: During the transition period of the lamp characteristic added to the transmission pulse, modulated frequency sweep is stopped to fix a modulated frequency. Hereby, a band in the transmission pulse is protected, and expansion of the compression pulse, namely, deterioration of the distance resolution is suppressed.

摘要翻译：解决的问题：为了解决这样一个问题，即在将发送脉冲的头部和终端添加灯特性的方法用于瞄准时间旁瓣抑制的问题中，在雷达装置中，以脉冲宽度施加可选择的频率调制的信号被发射到空间中，并且来自目标的反射波被接收并进行脉冲压缩处理，即使在该方法中添加的灯特性的过渡期间内也继续进行频率扫描，以及从而传输脉冲中的有效频带被破坏，并且压缩脉冲宽度扩大，即距离分辨率变差。
解决方案：在添加到发送脉冲的灯特性的过渡期间，停止调制频率扫描以固定调制频率。因此，传输脉冲中的频带被保护，压缩脉冲的扩展，即距离分辨率的恶化被抑制。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To expand a maximum search range and a maximum measurement doppler velocity without increasing a peak transmission power or a transmission pulse width, in a linear FM modulation pulse compression radar system.
SOLUTION: In a pulse compression radar system, a modulated pulse with a linear FM modulation in a pulse width is emitted into a space with a frequency sweep direction inverted per transmission repetition cycle period. Concurrently, a non-modulated pulse having a carrier frequency different from that of the modulated pulse is emitted into the space at a period shorter than the transmission repetition cycle period of the modulated pulse. A first pulse compression processing part which pulse-compresses a reflected wave from a target with a compression coefficient in the frequency sweep direction same with that of the modulated pulse and a second pulse compression processing part which pulse-compresses with a compression coefficient in the reverted direction are provided. A primary and a secondary echos are classified using the pulse compression processing, i.e. signal selectivity in matched filter processing, and the latter is connected to an end of the former to obtain a reflected signal of which the maximum search range is expanded.
