Embodiment Construction

[0079] figure 1 The structure of the two non-coherent transmit-receive units NKSE1, NKSE2 and their preferred interaction and signal processing as components of a distributed radar system are schematically shown in order to show an exemplary preferred basic structure. In the following, the transmitting and receiving units NKSE1, NKSE2 are always to be understood as non-coherent transmitting and receiving units NKSE1, NKSE2.

[0080] The two transceiver units NKSE1, NKSE2 are arranged in particular spatially separated. The transmitting and receiving units NKSE1 , NKSE2 exchange signals with each other, which also include signals with information or data contained therein about the paths SP, which are designed in particular as air interfaces. In addition to the signal transmitted on the direct path by the other transceiver unit NKSE2, NKSE1, an indirectly transmitted signal is also received in one of the transceiver units NKSE1, NKSE2, which signal is reflected on the object al...

Abstract

The invention relates to a method in a radar system, in which: a first signal (sigTX1) is generated in a first incoherent transceiver unit (NKSE1) and is transmitted, in particular transmitted, through a path (SP); generating a first signal (sigTX2) in another, in particular a second, incoherent transceiver unit (NKSE2) and transmitting, in particular transmitting, said first signal through the path (SP); forming a comparison signal (sigC12) of the first signal (sigTX1) thereof with such a first signal (sigTX2) received by the further transceiver unit (NKSE2) via the path (SP) in the first transceiver unit (NKSE1); and forming a further comparison signal (sigC21) of its first signal (sigTX2) with such a first signal (sigTX1) received by the first transmit-receive unit (NKSE1) via the path (SP) in the further transmit-receive unit (NKSE2); wherein the further comparison signal (sigC21) is transmitted by the further transceiver unit (NKSE2), in particular communicated to the first transceiver unit (NKSE1). A further design is a radar system or a device of a radar system, which implements such a method.

Description

[0001] This application is based on the application number 201580026040.6 (the international application number is PCT / DE2015 / 100119), the filing date is March 23, 2015, and the invention title is "Method, Radar System or Apparatus for Radar System" in China A divisional application filed by a patent application. technical field [0002] The present invention relates to a method in a radar system, a radar system or a device for a radar system. This applies in particular to radar installations with distributed transmitter-receiver units. Background technique [0003] A distinction is made between primary and secondary radars in radar technology. Primary radar means a radar device that analyzes the passively reflected signal echoes of previously transmitted high-frequency signals. In the secondary radar, the high-frequency signal previously transmitted by the first radar unit is received in the second radar unit. The second radar unit then actively sends a reply signal back...
