<p>PURPOSE:To shrink the scale of a radar device by using a common local oscillator, and providing a plurality of antenna systems with different pulse compressive modulation systems for the output signals of transmitted signal generators having an identical center frequency. CONSTITUTION:The output of No.1 signal processing device 8a, output of No.2 signal processing device 8b, and output of No.3 signal processing device 8c and No.4 signal processing device 8d are displayed in a display 16. In case, for example, a transmissive signal of No.2 antenna system is included in No.1 antenna 1a, it passes through No.1 circulator 2a and frequency converted by No.6 frequency converter 3a with signals from a local oscillator 9 to become IF signal. This IF signal is also amplified by No.1 IF amplifier 4a and distributed by No.1 distributor 2a. Because the modulation signals of center frequencies f2, f4 have different center frequencies, they do not pass No.1 pulse compression filter 6a and No.2 pulse compression filter 6b. Thus mis-acknowledgement can be avoided.</p> |
