Definitions
- the invention is based on a pulse radar arrangement, in particular for short-range pulse radar applications in motor vehicles.
- High-frequency source for controlling the mixer on the receiving side only has to be provided once.
- the operating mode can be changed flexibly:
- Figure 4 is a block diagram of a pulse radar arrangement according to the invention with several receive trains.
- the delay circuit 211 is required. After a defined time after the generation of the transmission pulse, which corresponds to the pulse transit time for the desired distance cell, a very short scanning pulse is applied to a broadband scanner 413 or 414 and samples the output signal of the IF amplifier 411 or 412 in the selected distance cell , The length of the scanning pulse is of the order of the transmit pulse and IF pulse width. This happens in the rate of generation of the transmission pulses, only delayed accordingly.
- the variation of the delay time allows the scanning of the desired distance range identical to the SRR (Short Range Radar).
- the scanner detects voltages different from 0 and thus recognizes the pulse return after the desired runtime.
- Non-coherent pulse integration is possible which improves the signal-to-noise ratio in proportion to SQRT (n), where n is the number of integrated pulses.
- FIG. 4 shows an exemplary embodiment with several receiving trains, here specifically two.
- the individual receiving trains can be designed as in FIG. 2 or 3.
- the receiving trains shown in FIG. 4 differ from FIGS. 2 and 3 as follows:
- each mixer 4, 5 and 41, 51 has a separate pulse modulator 71, 72 or 711, 721, which is independent of the respective.
- other mixer of the same receiving train can be controlled via a corresponding pulse signal source 11, 12 or 111, 121, delay circuit 21, 22 or 211, 221 and receiving gate 212, 213 or 214, 215.
- the individual receive trains can either have a common receive antenna 61 or each have separate receive antennas 61, 62, 63.
- further downstream signal dividers 81, 82 are required ,
- a superposition of two orthogonal codes can be provided in the transmission train and only one of the transmitted orthogonal signals can be evaluated for each reception train.
