Abstract: For suppressing secondary lobes in pulsed radar systems, the antenna characteristics of the transmitting antenna and the receiving antenna are designed so that the dominant secondary lobes appear mutually offset and their maximums and minimums are mutually suppressed. This increases the safety against detection of false targets.

Abstract: A pulse radar system has a high-frequency source, which supplies a continuous high-frequency signal and is connected on the one side with a transmission-side pulse modulator and on the other side with two separately controllable pulse modulators in at least one receive path. Mixers are situated downstream from pulse modulators, respectively. The mixers evaluate a radar pulse reflected by an object together with the signal of the high-frequency source. The pulse radar system allows different modes of operation that may be changed in a simple manner.

Abstract: The present invention relates to measures that enable simple assembly of a high-frequency (HF) module. The HF module includes a HF circuit board (1), on which at least one first antenna part (6) is located, a housing part (2), on which at least one second antenna part (7) is located, and a shielding cover (3), whereby the HF circuit board (1) is installed between the housing part (2) and the shielding cover (3). With the aid of the measures according to the present invention, the housing part (2) and the shielding cover (3) can be easily adjusted relative to the HF circuit board (1). A reliable connection between these three parts can also be achieved with relatively little outlay. To this end, the HF circuit board (1) includes, according to the present invention, at least one through opening (8), while the housing part (2) has at least one peg (10) which extends into the through opening (8). The peg (10) is connected with the diametrically opposed surface (14) of the shielding cover (3).

Abstract: A pulse radar system has a high-frequency source, which supplies a continuous high-frequency signal and is connected on the one side to a transmission-side pulse modulator and on the other side to at least one mixer in at least one receive path. A pulse modulator is connected upstream of the mixer with regard to its connection to a receiving antenna. The mixer evaluates a radar pulse reflected by an object together with the signal of the high-frequency source. This system does not require a ZO switch and is insensitive to interference.
