摘要： Das Impulsradarsystem weist einen nach dem Prinzip der Impulskompressionstechnik arbeitenden Sender und Empfänger auf. Um mit geringem Aufwand und unter Ausnutzung der Freiheitsgrade der Impulskompressionstechnik zusätzlich eine Steuerung und/oder eine Identifizierung der georteten Objekte zu ermöglichen, ist in den Sendeimpulsen (I) wenigstens eine Impulslücke (A) eingefügt, deren Dauer (τ) kurz gegenüber der Dauer (T) des Sendeimpulses (I) ist. Die Lücke (A) dient als Uebertragungskanai für im Strahlungsbereich der Antenne des Radarsenders befindliche Objekte und/oder als Identifizierungssignal für am Objekt reflektierte Echoimpulse. Dem eigentlichen Sendeimpuls (I) wird dabei durch mindestens eine Impulsiücke (A) eine Information in kodierter Form aufgeprägt.

i , c2
i ,..., cN
i ), one distance bin corresponding to each of the N pulse compressions, the combination function depending on the rank of the distance bin in which said function is applied, at least three distance zones being defined beforehand, the result of the combination function is: - the compressed signal of the last sub-pulse for the distance bins corresponding to the small distances zone; - the minimum of a function with amplitudes Ai of N compressions for the distance bins belonging to the medium distances zone; - the mean of a function of the amplitudes Ai of the N compressions for the distances bins belonging to the large distances zone; Ai being the amplitude of the compressed signal for the i
th sub-pulse.

摘要： A radar apparatus using a pulse compression technique, in which any automatic response signals are prevented from creating false radar images on the indicator screen of the radar apparatus. An antenna repeats a transmit/receive cycle at a second time interval while rotating, in which i) a non-modulated pulse is transmitted, ii) a modulated pulse is transmitted a first time interval after the transmission of the non-modulated pulse, and iii) an echo and/or an automatic response signal occurring after the pulse transmission is received. For each transmit/receive cycle, a first separated receive signal having a frequency band corresponding to that of the modulated pulse and a second separated receive signal having a frequency band corresponding to that of the non-modulated pulse are separated. An elimination process is applied to the first separated receive signal, in which respective first separated receive signals for two consecutive transmit/receive cycles are compared and any signal component having discontinuity between two consecutive transmit/receive cycles is eliminated from the first separated receive signal. A pulse compression process is applied to the first separated receive signal having undergone the elimination process. The first separated receive signal having undergone the pulse compression process is combined with the second separated receive signal.
